Updating multiple Bookings Apps at the same time

We are exploring the possibility of using Microsoft Bookings to manage some appointments and one particular scenario we may end up with is where we need multiple (30+) identical bookings forms, with different users associated with each.

If we go down this route, which isn't definite yet, is there a way to update all of the forms at the same time? From what I can see each "instance" of Bookings is separate, but I was wondering if there was some way, possibly using PowerShell, of updating the details/settings of multiple forms together, instead of updating multiple forms independently?

An example of this might be if we had a standard appointment for 30 minutes, and we want to extend this to 45 minutes. Instead of updating each page individually, is it possible to run a command to update all at the same time?
