Can I remove "start time for each booking"?

Hi, I wondered if this was a new feature on YCBM for “start time for each booking” as it seems to have screwed up my system that has been working well for the past couple of years of using the platform - is there any way to disable it?

I run 45 minute slots over a day (7 or 8 in total, with a variety of breaks in between.

@ChrisSP I am sorry on the long delay here. You may want to explore or allow a start time every 15 minutes to accommodate your duration and the flexibility of them starting at any 15 minute interval.
