Feature Request Desktop Folders Portal

Hi there, I have a desktop fence in which folders are sent to, I just wish that fence could have the functionality of a folder portal, allowing navigation within the fence itself.

I've gotten round that by making a desktop portal for the desktop itself, although it contains everything else other than folders themselves.

I think as a feature request the simplest way to implement what I want, is could we have extra folder portal functionality? As in could we have folder portals that only show folders within them and vice versa, folder portals that don't show directories and only files?

Thank you
