Stream Ownership

Hi everybody,

our RTC environment is managed through Team Area under a single Project Area.

Project Area obiviously doesn't have any member cause every user is allocated under the proper Team Area.

Each Team Area owns and uses its stream.

We'd like to share a stream (promotion central stream) and we thought the best way to do it is to give the ownership to the Project Area. Wrong! When we try the "change flow target" to the shared stream we get a "permission denied". Details:

Problem
You don't have permission to Deliver [server].

Reason

Where exactly we are doing wrong?
