how to use objects obstructed by container?

I'm trying to control a multiball that is completely obstructed by a container, however, I'm finding that the balls can't be manipulated unless at least some of the multiball window is visible. I'm also open to the idea of not obstructing the multiball window, but having the balls (and their paths/tethers) entirely invisible. Pretty much, I'm looking for some kind of solution to manipulate the MBs without having them visible. Much appreciated!

You can just overlay the multiball with a canvas object set to no touch, and color the canvas any color you want to.

Cheers!
