The command handlers don't have a reference to any specific piece of UI. You will have to get a reference to the button tools you added to the toolbars manager and set their properties manually.
The UltraToolbarsManagerWorkspace is a derived UltraToolbarsMananger, so you will be able to access the same properties on it.
Sorry, I meant through programatically via code.

How do one do this via CAB in one of the controller?
