Shared controls for multiple video/audio OPs

I’m trying to build a video sampler with simple shared controls (record, play, stop, pause,etc). The current issue is that I can’t seem to find a way to route the controls to the appropriate base. A switch lets you pick input but not the output. In this case, there’s only one input, the controls, that need to go one of many bases. I need to flesh out the workflow a little but essentially a toggled button is what should determine where the control messages go.
