Ratgdo with 888LM and extra push button

I installed a ratgdo on one of my garage doors that I had previously installed an 888LM pushbutton controller on in order to get security+ and MyQ working. It works fine and I am having no issues with the install. Now I want to add a second button to operate the opener from a second location on the other side of my garage. Originally I thought this was already supported but now I only see how to wire up multiple buttons, one for open, one to stop, and one to close. Is there anyway to add a single momentary button wired directly to the ratgdo to work this way? If not, I do have a zigbee button but I don’t really see that single button functionality build in to ratgdo digitally either? Any ideas or do I have to duplicate that logic in HA?

Thanks

For the zigbee button just program single button function into an automation
If it’s open the button closes
If it’s closed the button opens
If state is unknown, I would default close to be safe.

I expect you will be there while ooerating from button so if any problems you can deal with it

Simply make a cover.toggle service call. It should work exactly as desired.
