[Fenix 7] Receive GPS signal from phone / override internal GPS?

Hi everyone,

Do you know if it is possible to force the garmin watch to use GPS signal from phone (connected to the watch by bluetooth) instead of the watch's internal GPS sensors?

I like to swim with the watch but the water blocks the GPS signal completely. I would like to be able to get GPS from the phone that is floating in the bag I have with me.

Other garmin watch models have this feature (the ones without internal GPS) so I'm guessing this shouldn't be anything too complicated.

Many thanks!

Marek
