Right click doesn't work for Found In query

Here's the problem that I'm trying to solve.  We have multiple releases going on during an iteration using the same team.  Some releases have items that will take longer and need to get started during the release cycle of another release.  We've tried configuring RTC in all kinds of crazy ways.  The best idea so far is to add the Release to Story, Task, and Epic and use it to define the Release that is being worked on.  However, it breaks down when previous work items need to have the Found In changed through the query results.

Details:
I'm using RTC 3.1.0.6.  I have a query that provides a list of work items (defects, tasks, stories, and epics) and displays the Found In (Release) column.  I want to Right click and Change Found In to a different release.  I can do that with Status, Type, Owned By, etc.  However Found In is being treated like Id and Summary.  I can understand not wanting to do a global change on Id and Summary.

What do I need to do to get Change Found In right click enabled?
