So I can create a custom field to store a type

Document

. Is there a way to create a field that will store a folder location?

You would create a text field to store the folder ID and then use that ID when you do things w/ a file that need a folder

That’s what I ended up doing. It works fine. Just easier for the user to mess it up accidentally. thanks @creece

You could consider setting the display type of the text field to hidden, creating a select field and populating the options using the results of a search using a beforeLoad script, then setting the value of the hidden text field based on the selected option in a beforeSubmit.
