Is it possible to change the desktop directory in TDE?

Hello all, I undestand the question may look strange, so here are a few explanations. I have a laptop (Thinkpad X220 Tablett) that I use at work. As you guess for "normal" work I use TDE, but unfortunately I found out that I can't use the touchscreen well with TDE. If I rotate the screen I can't calibrate it correctly (the pointer coordinates don't get rotated at all, so pointing up right shows the pointer left down...). A recent install of openSuSE Leap 42.3 let me discover that Gnome 3 (Gnome Shell 3.20.2) has a Wacom calibration tool that solves this issue perfectly. I've even managed to run konqueror as file browser from Gnome's Dash, but I still prefer TDE. So my present solution is to run TDE and TDM, and to logout/login in Gnome Shell when I need the Wacom Tablett. There remains a (small) annoyance: I've set up three links on my Desktop (to a local directory and two NFS shares) and they appear as useless files on the Gnome Desktop. Obviously, both TDE and Gnome use ~/Desktop as desktop folder. There does not seem to be any way to tell Gnome to do otherwise (there is little way to tell Gnome anything, seems), so I wondered if maybe Trinity can bw told to use another directory as Desktop directory?
