Reply to How do I switch between remix decks?

Using the default remix deck settings for the spectra, you can initially select which deck you want to control by pushing one of four buttons representing a deck. After that, the buttons control the slots. How do I get back to that initial page to select which deck that I want to control? I believe I saw in the manual that I need to add a few commands to do this? If so, to what device do I need to map those to?
