Markup Rotation

I've recently purchased the Tourbox and love using it for all my Adobe editing programs. It also lets you create custom commands for other programs. I have been assigning shortcuts for Bluebeam to it and like with the Adobe products it saves me time.

One of my holy grails would be to assign a shortcut to the rotation of a markup. In my case, it's the view of a security camera shown by a custom tool I made. I can't find anything on a hotkey to the rotation under the layout and or for its two up and down buttons used to rotate the markup. Does anyone have any advice? By the way, go get a TourBox they are awesome!
