String variable as path in editor panel

Hi,

Is it possible to set a string variable as a path of a file from your computer in the editor’s panel parameters? I saw the documentation for the UPROPERTIES but found nothing.

It would be very useful for fast testing of external resources(not assets in the editor) like : audio files, text files that have to be parsed, etc

I’m for the moment manually copy pasting the path from my computer in the string parameter box, but that’s a bit repetitive and slow.

Thank you.
