Auto-swap bikes as a feature?

The recent Stage 4 of the ToW got me wondering - is there any way of developing a feature where you can load up a secondary bike ready to go and then toggle between them using a button in the companion app or a keystroke? That would make routes that involve any of the gravel in Watopia or Makuri a lot more enjoyable than either a) slogging on the bike that makes sense for the other 80% of the route, or b) coming full stop, switching bike, starting again.

At this time you there isn’t.

You used to be able to change bike without buying to a stop by going to the garage but it was changed to not allow this until you had stopped.
It was effecting race results that had mixed terrain or altitude.
