Removing a stream from the Pending Changes view

Hi,

This is going to seem silly, but there has to be a solution:

There is a stream which I rarely have to deal with. When I do, I am pushing changesets from that stream to the flow target.

I right click on the stream -> Show Pending Changes.

This puts the stream into my pending changes view. But it seems to be there forever from now on. How do I remove that stream from my pending changes view? I only want it there some of the time, not all of the time

I can't find any way to remove a stream from my Pending Changes view once I've shown it.

Thanks,
Greg
