How can the default start-up door be changed?

How can the default start-up door be changed? I have 3 Garadget devices and am tired of having to select the Main door from the lower row when I am opening the app.

Seems like it should be a simple fix, but I am unable to find a solution in the app settings.

Any suggestions?

Are you on Android or iOS?

Android Note 8

Thanks for the info. I’ll pass that on to the app developer.
