Link a Knob with two or more parameter

This is quite old thread but I have a similar problem. When I want to connect a knob or a button to let say Audio Warp speed or any parameter in modulation matrix, Macro Designer connects that knob only to a single wave file I have inside a layer. I have hundreds of samples inside my layer and it seems I’m able to assign controller to only one.

Is there a way to make it work in Macro Designer ?
