How to set multiple project owners in MS ProjectServer

I'm trying to configure a owner-like user in MS Proj开发者_Go百科ectServer (2003). Though I can grant every permission to the user, for certain services (via PSI), like Statusing.ReadStatusTimephasedData, it seems to require to be the project owner.

I've tried to configure category permissions to consider RBS but no results either.

Any ideas?

There is no way to achieve this! I have developed a PSI extension to get the data I need.
