Add-on domain's change document root from file manager?

http://forums.cpanel.net – Hello everyone, While altering the add-on domain name document root, I get a dialog (see attached screenshot) to change the document root location by entering it manually. Is it possible to display it on the file-manager so that a user can change it via the file manager gui (maybe an addon)? Attached Thumbnails   (HowTos)
