Enhancement Ideas for Bulk Work Item Edit

I have been presenting RTC 3.0.1 to customers recently. During these demos, the customer asked for additional functionality of the bulk work item edit feature.

Specifically, what has been asked for:
- create/delete links (from multiple work items to a common target work item)
- add/remove subscribers
- add a comment (in addition to bulk property change or in combination with above actions)

I would like to know if any of these ideas are already being considered for the 2012 release. If not, I'd like to create an enhancement request for these.

Please share your thoughts!
Thanks,
Markus
