Mobile Business Appointments need an Address

My business is booking appointments at our clients’ homes or offices - and on video calls still too.  Am I right in in seeing that this scheduling system 

a - does not allow us to manage the client’s address on their contact info

b - does not allow us to add the address to the calendar

c - does not allow us to share a Zoom / Teams link in the appointment

I’d love advice for how any of you have dealt with a similar situation.  

We often meet clients at their homes or other out-of-office locations as well so I hope there's a way to include the address.
