Add additional data to filter results

Good day awesome people!

I have a dev question which I need resolved ASAP as I am pushing against time.

Q 1: How can I configure the plugin to dynamically add a location (I got 9 provinces to create)
Q 2: How will I be able to insert that into my appointments page, so that when a user selects a location, they will then be able to select the service and only a service provider for that specific service in that location will show?

I hope to get a response from you soon!

Kind Regards
