Yes, you can try it yourself.
For example:
* Press the properties button on a not assigned macro knob, that open the properties popup
* Press "Add..."
* Drag all tom channel volumes to bottom
* Press "Save Start"
* Drag all tom channel volumes to a volume that you want to be a maximum
* Press "Save End"
Now your macro control should change volumes of all tom channels in the mixer.
