Dynamically add options to dropdown via URL parameter

Hello! I am working on a medical provider profile template for our group that will let users view each doctor and request an appointment (via JotForm) at a certain day/time/practice location. I am going to use one form on all doctor pages by embedding the form in our php template. Let's say Dr. Bob has 4 locations. I would like to add his four locations as options in a dropdown. Can this be done via URL parameter?

I'm thinking technically here. What if I populate a hidden field with the location values via URL parameter. Can I take the options in the hidden field and make those options in the "Preferred Location" dropdown?

Thanks!

Thank you for contacting us.

With prepopulation by URL parameters you can select one of existing Drop Down items, but I doubt about adding new items.

It should be possible to edit Drop Down question items via API, so you might consider if this is an option in your case.
