TR8S question changing patterns from pyramid?

Hey guys, getting the tr8s and pyramid to finally talk to eachother, i’ve got everything so that I can sequence drum patterns on the pyramid to the tr8s, lots of fun. Was wondering if there is a way to use the pyramid to change variations (the a-b-c-d-e-f-g-h buttons on the tr8s) on the tr8s? any help would be appreciated, thanks!

Nothing in Roland’s documentation for the TR-8S indicates that variations can be selected using MIDI messages.
