Quick switching between plugin collections

Hi folks,
does anyone know if there is a way to quick switch between plugin collections? I have a Behringer X-Touch and when all my plugins are in one list the rotary encoder skips 3 at a time which renders it a bit useless (no idea why). I remedied the issue by splitting the list into two collections. The rotary now scrolls through all the plugins one by one in each collection which is great but I want to be able to quick switch between the collections. I hoped there might be a mappable key command but I can’t see one. Am I just stuck with mouse-ing the collections? Cheers in advance.
