Much expanded role, same title

Currently I'm based in HQ but have a regional role in pre-sales where I manage  5 individuals. We acquired a company in a country in my region during the past year and we need to relocate an experienced individual who can bring the office into the corporate culture and strengthen the office so that we can start to see significant ROI.  In 2 months I'll be moving to the office in order to be the senior figure in the office. The office is comprised of about 30 people and we intend to grow that to around 45 while doing some housecleaning. Only one person in the office is a part of my regional team. The rest of the employees report to other parts of the organisation. The KPIs I'll be judged upon with regards to the office include:

• Profitability (I'm not given a budget, but will be expected to regularly report to executive management on things we can do to impact this KPI)
• Retention
• Top line sales (The salesperson is the one responsible for selling, with my support)
• Sales pipeline (Marketing, with my support and guidance)
• Signing an alliance agreement with a partner in the region
• Ensuring that executive management has visibility into the activities in the office and that the office is kept abreast of what is happening elsewhere.

To me, my manager in my current role, and my colleagues, this seems like a promotion with more responsibility. The person who is setting up the terms and the KPIs is the manager of my manager. He doesn't see this as a promotion but merely the senior figure in the office whose opinions and actions will carry a lot of wait.

Most all topics regarding the relocation and responsibilities have been settled. The one topic that I'm having trouble with personally is the title. On the one hand I feel that I'm being silly. What does it matter what title I have so long as I do a good job and others understand that I've taken on more than my current role. On the other hand if I'm being asked to take on an expanded role I feel that I need a title that is appropriate.

Currently I'm Regional Director of Presales. The suggested titles have been Country Manager, <Country>; General Manager, <Country>; Managing Director, <Country>. Office Manager would not be good since it would be considered an admin position in this country. The suggestion of my manager's manager is Director, <Country>

Why do I want the title?

• It will help when meeting with people outside the company as they will understand that I'm not just pre-sales but have a larger role.
• When speaking at conferences it shows seniority when is important when you are speaking alongside C-levels of companies.
• Within the context of the new office it will give me influence by virtue of position while I'm earning the influence based on contribution.
• Others in the company, outside of my region, will understand that I now have an expanded role.
• It will look good on my resume and fit in more naturally with the MT achievement bullets.
• It will make me feel appreciated without costing the company anything.

Why does my manager's manager not want to give me the title?

• No other regions/office have someone with a similar title. (Also nobody else is responsibile for a breadth of KPIs like these including profitibility)
• I've only committed to the relocation for a year and he's worried that if I leave the position after a year he will be forced to cater to someone else in the office that wants to be promoted into that position.

Am I just being silly?
