Is it possible to use a Saved Search as a filter or a script to filter locations on a form by the class? I can auto select the class based on user / role, but I want to filter the locations to just those that match the class. I created a custom field on the location to assign the class to location.

On the Form Customisation you can add a longing search which will limit the items BUT it’s not dynamic. For Class limitation would it would for you to instead limit their Role or Employee record?
