Nothing that I know of but, you can amp the same midi control to do multiple things in loopy so 1 button press could do everything you're asking.
Remember you can add foot switches and get 8 commands going through a single blueboard
I'm also not sure you can run 2 blueboard a at a time if you can let me know I'd love one doing programme changes and 1 doing command changes
Standard, I've used it with a crappy bespeco expression pedal, you just have to remember to calibrate it in the blueboard app.
I think the line 6 or boss expression pedals would probably be fine for it.
