ID 141139 - Adding tags to multiple track items is not treated as a single undoable event

Problem summary
Adding tags to multiple track items is not treated as a single undoable event, meaning that the user needs to press Ctrl+Z to undo each individual tag.

Customer reported version
Hiero 16.0v1 

Customer reported platform

Rocky Linux

Steps to reproduce

1) Open Nuke Studio.

2) Import multiple clips (File > Import File(s)...) and drop them on to your timeline.

3) Select all of the clips on your timeline > right click > Tags > Tag Shot Selection.

4) Press OK in the dialog that appears, to add the default tag.

5) Press Ctrl+Z and notice that only one tag is removed at a time.

Expected behaviour
All the tags should be removed in one go.

Actual behaviour
Even though the tags were added in one step, you then need to undo each tag individually.

Workaround
You could add the tags via Python, and group them under a single undo operation. For example:

proj = hiero.ui.activeSequence().project() proj.beginUndo("Add multiple tags") tag = hiero.core.Tag("test") sel = hiero.ui.getTimelineEditor(hiero.ui.activeSequence()).getSelection() for item in sel:     item.addTag(tag) proj.endUndo()
