Family accounts for Garmin+

Could you add support for a family account for Garmin+ such as being able to share the benefits with spouse and kids? Apps purchased through iTunes/Applestore allow me to share with family but with everyone moving to subscriptions it quickly becomes non economical for families.  it would be nice if Garmin+ could be shared with family members. Seems like Garmin could add a family group function with ability to invite 3 other members and share benefits easily.
