Undo of all played macro commands at once

[myss]

I have created a complex macro that includes text inserts, deletions, cut and paste. If I execute the macro and want to undo it, I have to press ctrl-Z multiple times. I think that it would be better if everything would be undone at once.

There seems to be an object named something like EnvDTE.UndoContext that has Open(actionLabel) and Close() methods as well as an IsOpen property. But I can't figure out where to get that instance from.

It would likely go into the MacroCommandFilter.Playback method. Unfortunately I can't try out this extension because Visual Studio 2015 won't start it. (I'd expect it to run it in an experimental VS instance but this one doesn't work.)

Just tried it without the safety net, and it worked. MSDN told me where to get the required parts.
