Feature Request: Combine Two SwitchBots into one Accessory? 
### Describe Your Problem

To open my garage door, I use two SwitchBots. Is it possible to expose the two accessories as one in Homekit? To open my garage door, the first SwitchBot has to turn on the intercom before the second opens the gate. I can easily expose my individual SwitchBots as Garage Doors in Homekit, but need to combine the two accessories into one for it to actually work.
