Helpers convert a 2 Button controller to a cover

OK so my garage door open has discrete Open/Close/Stop so to Automate my door I have a 4 button relay from sonoff I use Button 1 for Open Button 2 for Close Button 3 for Stop but not really needed and Button 4 is not in use
Is it possible to combine Button 1 & 2 so it show as a cover in helpers so that up is button 1 and down is button 2

Also looking for this. I have a 3 button controller: Up/down/stop.
I have 3 buttons in HA from an RF bridge but am not able to create a cover out of these.
