Selective export to Strava
 

I suspect that what I want to do isn't possible but here goes anyway.

I've been using a Garmin Edge since 2008. The data from this automatically exports to Strava as I have a bunch of friends I share with.

I recently bought a Garmin VivoSmart fitness tracker (mostly to get a discount on my health insurance, although it has been more fun to use than I thought it would be). The thing is, though, when I go for recorded walks (as opposed to general background activity) these are also getting exported to Strava. Is there any way I can choose to share data from one device with Strava but not the other? Or alternatively tell Strava to import cycling data but not walking?

Cheers
