I tried using the printer settings plugin for this but the diameter setting is locked. But I think this works, go to machine settings and change the gcode flavor to marlin, then click the extruder tab and modify the diameter, then go back and change the gcode flavor back (to UM2 in my case) Even though the editable diameter box under the extruder tab disappears the diameter you enter under the marlin setting will carry over and be the new default for all materials.
