Different Logo for each clinic

It would be very useful to be able to have a different logo for each clinic on the system. We run two different businesses at one site, each having their own logo/branding. We are able to name them differently, have different appointment types, but online booking uses one logo for all clinics. We also have another clinic at a different location which also operates under separate branding. We don't want to have 3 different PH accounts to service these, it would be much smoother for us to operate under one log in, but different branding.
