Getting commands to work with SFX SmartDashboard

[AtomicBrawlers]

I'm trying to get commands to work with the SFX SmartDashboard. I can't figure it out for the life of me. To be clear, by commands I mean the widget you can add to the dashboard that is literally called a "Command." I want to be able to press the play button and have something happen then press it again and have something stop.

I don't see any way to give a command a path nor do I see a way to change something coming from Incoming into a command. Maybe I'm not going about this the right way? Any and all help is appreciated.

P.S. Does anyone know the difference between Passthrough, Nested, and ForceNested?
