Multiple configurations are best handled with heavy drinking , and experience in programming, and more drinking.
Nobody does either well.

Resign yourself to several minutes setting up and verifying any setup you change.
The folks that are happy with their set ups seem to not have many ,and have stable configurations.
Complexity adds variables in an exponential fashion.

If you get 80% performance, you have beat the average, bigly.
Nobody appear to have cracked the code for multiple bikes with differing sensors.
It appears to be a bigger programming challenge with more variables than can be easily sorted out.
Best approach I have found (3 bikes and trainer),, is to make a checklist of the things you want to review before use.
Only adds 5 minutes to a pre ride prep
