How to display full file path in a TV

I'm working on a MODx site (2.1.5) where I've got a TV for file uploads for each MODx document. The client will upload pdf's and such through this TV. Works fine, but the problem is showing the full file path so they can copy/paste the file path into text for linking. I've turned off the RTE and am using Textile in it's place to keep the site content clean (got several managers adding content and striving to keep the look consistent). When uploading the document, we upload and upon choosing it, it simply shows "filename.pdf". Instead it would be nice to show "full_filepath_to_doc/filename.pdf". So in this example, we have a directory for the clients to store their docs and it resides here "public_html/asldk3dl/user/" (we've customized the assets path/url)... so ideally when they choose their doc, I'd like to show that file path: "asldk3dl/user/filename.pdf" so they can copy/paste that into their text area.

Just not sure how to get the filepath to the file to show in the TV area.

Thanks!
