Can't "undo" rename assets using editor utility widget

[TheFlyingEpergne]

Wrote this script to rename multiple files. The renaming aspect of it works perfectly but when I tried to implement the “undo” function it just doesn’t work.

The action doesn’t show in the edit>undo menu at all.

Any idea why? I can “undo” actor actions but seemingly not asset actions.

Have you ever found a solution? I use transact and “Create Copy for Undo Buffer” with every kind of asset edit, but apparently renaming assets doesn’t mark them as dirty and I can’t undo the operation!
