Multiple Owners and Subaccounts

Please prioritize building functionality that allows multiple account owners and/or sub-accounts. I cannot stress the need for this functionality strongly enough. As a homeowner who shares the financial, child-rearing, home maintenance, and every other responsibility with my spouse, I cannot imagine them not having the ability to monitor and control our home security system. 

I was absolutely dismayed to learn that I cannot perform this incredibly basic function upon setting up my system today and am seriously considering asking for a refund. I just cannot believe that this feature does not exist. Please add my name to the list of other disappointed users who have requested this functionality for years now. Additionally, I'd genuinely like to be included in any sort of beta user/testing program if you have one.
