[Undo] not undoing change to NPs when change goes from home to manual

Not sure if this is a bug report or feature request.

Channel 1 has color data that is at home values, not receiving data from a cue, sub, or manual values.

I give it a color palette manually.

Then I hit [undo], The color doesn't change, it just becomes un-manual.

It should go back to its home values.
