Undoing changes to parcel-based code

It has been decades since I've had to seriously maintain code from a change set rather than from a code repository. Even VW code (not just application code) had been published in Store so that changes would be obvious and accounted for. Last week I ran into some problems with Store-represented code using VW 7.7.1. One workaround I'm exploring is to not use Store as much as we had for VW 7.5. I'm wondering though, how changes to parcels can be undone.

For example, I made a simple change to code represented in a parcel. I can see the change and what it was changed from (Browse->Changed methods.. then "Browse Method Change"). I can't really revert to the previous version though; the "replay" of a version just creates another change. I can't reload the parcel (to make it clean again). If I re-save the original code it is still a change. I looked into the "forget" changes kinds of options, but it applies to ALL changes rather than the specific ones I care about. So I'm wondering...

If you change code that is only parcel-based, how do you undo that change later so that the parcel is back to a clean load? Right now, it looks like the only way is to start over with a new image (and change file).

I make temporary changes to base code quite often. Rarely do those changes last more than a couple minutes before they are reverted.  It isn't helpful if every parcel grows to indicate it has changes when really it doesn't. It isn't helpful when I browse changes and see methods that had been reverted to their original definition.

Any tricks I should know about, for reverting *specific* changes managed from a change set?
