Command Manager Dropdowns (or reset)

Hi,

I'm on SW2016.

I was messing around with customizing my command manager's Sketch tab and managed to delete some items that aren't individual commands, but rather command groups.

For example, I deleted the "Move Entities" item which is actually a dropdown that has several transformation commands available.

I can't figure out how to either reset the Command Manager to factory defaults, or to create dropdown groupings of commands.  As a result, if I wanted to have all those commands back in the tab I would have to have them all separate.

For resetting, I've tried all the reset options I can find.  I've tried resetting the registry.

For grouping, I attempted the iOS trick of dragging one command onto another.

I couldn't make any of this work.

Help?
