Emergency Contacts with Multiple Phone Numbers

My wife and I work in areas that don't allow cell phones. Therefore, I need to create 2 contact numbers for each of us--one for the work number & the other for the cell number. The only way I can apparently do this is to enter my work number for the first contact, my cell number for the second contact & my wife's work number for the third contact. At a minimum, I need a fourth contact for my wife's cell number. Ideally, I'd like to have a total of six (6) contacts in order to add my adult son. My previous alarm system (ADT) allowed at least 3 numbers for each contact (3) and I could choose which numbers to call in sequence. Please tell me this will be possible SOON for Ring Alarm.
