Hi Nathan,
Creating two search fields is not possible for a single search bar. I mean, you can make as many search bars as you need, but they will work independently.
If the location is stored as a custom field, then using a custom field filter is a possible route for this. The filter type can be a “drop down” with a search feature, or a text input field as well. We have a very similar setup for the staff and search filter demo.
Unfortunately we are not available for customization requests.
