Can you inherit role and permissions from a master project area?

I am using RTC 4.0.1 and I have a master (parent) project area which has its process configuration inherited by a large number of child project areas.

The master project area has a number of different roles defined which are all inherited by the child PAs eg..

workflow_browse

workflow_edit

workflow_edit_2

administrators

As part of the administration team we have the task of supporting the many users in each project area and manipulating their work items with the certain privileged permissions we have assigned ourselves via the 'administrators' role.

Currently when our support is required we must find the associated project area and add ourselves as a member and grant the 'administrators' role in order to perform any tasks on the work items associated to that project area. This is very frustrating when having to support hundreds of different project areas! 

If I have my 'administrators' role assigned in the master project area, is there anyway to have this inherited or looked up by the work item workflow action before failing with the "permission denied" error?

Thanks, Alex
