Add more options on the "Select Your Preference" window before making a booking

I’m having trouble with adding an extra selection in the “Select Your Preference” window before making a wix booking. My services have add-ons and that’s the only thing i can select in that window before moving onto selecting a date and time.
Working in Wix Studio Editor.
What I’m trying to do is to be able to choose one of 3 rooms this podcast studio has, before they go ahead and book the date and time. So they can choose the room and any add-ons if they choose to.

What I’ve tried so far is creating a form for the service with those options, but it only shows at the end of the booking, and i can’t find a way to move that into a different step of the booking process.

Is this possible? Or should I just go with what I’ve been able to do, which is showing the option at the end of the booking?
