Disable NSUndoManager grouping invocations on document load

NSUndoManager groups invocations together that happen in the same runloop.

I want to load a document that contains the undo history within it.

As such, I create a document and apply the invocations one-by-one, these however all get added very quickly, resulting in a single undo.

Is there a way I can change the NSUndoManagers runloop or something else so that I get separate undo invocations?

I have tried disabling groupsByEvent and creating my own beginUndoGrouping but it doesn't seem to work

Have you tried closing the toplevel group and opening it again after you added your invocations? E.g.:

undoManager.endUndoGrouping()

// add your undo invocations

undoManager.beginUndoGrouping()
