Keep Third-Party App Profiles separate

I have several people that use the bike, now we are all leverage the same Netflix account; however, for Spotify, all the users have their own identity and login, it would be great to have each Echelon profile on the bike maintain it's own third-party app login so that the bike users don't need to log into the third-party apps with their own account, or switch to their profile. I would rather not have the kid's music selections start to impact my suggested music playlists, etc.
