This is a request we've received to allow more information to flow into a work item as it is being worked by developers. 
What would be involved to customize the check in process so that the comment is inserted into the history along with / or instead of the "Associated with changeset ##" text?
Is this something that could be done with custom checkin policy - I suspect not since that is used to indicate go/nogo on checkin.
Thanks

Addendum - just putting the checkin comment in the Comment field on the Link would be sufficient.
