Chain Rotation et al

It would be helpful to be able to add two or three chains to a bike and have a way to rotate them. Example clicking on chain 2 would automatically pause chain 1 and vice versa. Chain rotation is becoming more common as more riders are starting to wax their chains!!  Noticed this has come up in the past but I don’t see a response by Strava or in the program!  What up?  If you’re going to charge as much as you are you need to support longevity in the program otherwise why should people continue to use the platform?  Help us out please!
