Ideas to Handle City, State tags

Softr peeps,

I’m stuck on this one. I have users that add items to a list and they want to tag city,state to each. Later on users on the other side of the marketplace want to sort by or filter by city,state.

Because of the 100 API limit on airtable sync with softr, I quickly exhausted every city state on the drop down. Has anyone overcome this with something clever or custom?

Thanks,
Neil
