No method to set area mouse click emulation

Many touchpads are designed like the one below (this is a Toshiba P50-W). The expected behaviour is that pushing the touchpad down will do a left or right click depending on what side of the line the click is done on. This behaviour can be selected in "Mouse Click Emulation" in Tweaks. The default behaviour in GNOME is to use multi-touch to determine single click (one finger) or double click (two finger).

While it seems unlikely we can pick the "right" behaviour for all cases I think it should be possible for a user to go to the mouse settings and indicate their touchpad is like the pictured one and the behaviour to be changed.
