Maintaining Release Collection - Adds/removes requirements from RTC-Plan to a RRC-Release Collection

Hi ,

We create in RRC requirements , in RTC we create Stories and for each story we attach the needed requirements.

Then we create RRC-Release Collection and attach to it all the requirements we want.

If we create new Iteration and attach stories to the Iteration , at the beginning all the requirements are attached to the  RRC-Release Collection.

Then we add another story that has attached requirement or remove a Story with attached requirement.

How can I add/remove the Requirement automatically to the RRC-Release Collection ?

BR,

Chen
