Thx!

This does what I want for now, also setting the new ChangeSet as current, although any open ChangeSorters will not get updated:

ChangeSet newChanges: (ChangeSorter newChangeSet: 'tmpNewChgSet').

I've found how to update them if I could find the open ChangeSorters...

--
ChangeSorter>>newCurrent
	"make my change set be the current one that changes go into"

	ChangeSet  newChanges: myChangeSet.
	self update.  "Because list of changes in a category may thus have changed"
	self changed: #relabel.
