WebUI Sub-path browser/autocomplete

[s0beit]

I would like the Sub-path (pictured here):

To be a little more user-friendly. Right now I'm using the WebUI to initiate torrents which are saved to my HTPC. (Media center laptop). It's troublesome to have to type the entire name of the subfolder I need the files to be saved in. A simple file-browser (for just that one folder, or multiple ones?) or some kind of auto-complete (similar to the dropdown box that comes up when you're typing into google) would make the WebUI absolutely perfect for what I need it to do. It would be incredibly helpful.

If somebody can offer me an alternate [hopefully temporary] solution, that would also be nice.
