Permissions of a team member in iPhone Developer Portal

I want to know if there is a possibility to add a team member in iPhone Developer Portal that will have permissions (see / modif开发者_如何转开发y / update) ONLY to one application.

The reason - there is a big company (that has many applications in the App Store) that uploaded one of my applications and I have hard time to send an update to the application (can't access the guy that is responsible for all the iPhone applications).

I want to ask them to add me as a team member, but they might agree only if I won't be able to see/touch any other application except the one that I have developed...

Thank you.

I don't believe this is possible; there are no per-app permissions.

The available "roles" are explained here:

It seems a bit odd if they trust you to write an application that they've published under their corporate identity, but don't trust that you'll only change what you're meant to. Either way is seems the only solution to your problem is likely to be a non-technical one; you need to find a way to get to that guy, whether it's appealing to his better nature, or finding a path to someone more senior who can lean on him.
