Whenever there's more than one pad in the same group (eg. Wacom ExpressKey Remotes), show a popdown menu to allow configuring those extra pads. Devices are hot-pluggable, so the popdown menu will update its state whenever pads are added/removed. Also, allow to quickly change between pads by switching to its OSD by just interacting with them. Always given they are in the same group. https://bugzilla.gnome.org/show_bug.cgi?id=779986
