Hi JondyL!
Just wanted to let you know that we shipped a fix for your first point today.
For number 2, you should be able to set your booking form to be the one on the side navigation under Settings > Client hub, Request and booking forms. As long as you don't share your booking form anywhere publically, it would be only for existing customers, but as soon as a new customer sends in a request they could technically go into client hub and see the booking experience.
Thanks for the feedback on duplicate properties! We will continue to make improvements to duplication detection.
