In the mean time there is an easy enough work around; Just go into your Duty Support and select unsynced then select whichever dungeon your wanting to run (that Miqo can run with duty/trust) then close out the window. Then go into Miqo and make sure you select that Dungeon under combat tab. Next go to your game keybinds; gamepad tab; and set {X Button} to something not used; I use {Shift+F9} then run this custom script:
sendKey(u, 1.5)
sendKey(shift+f9, 1.5)
sendKey(shift+f9, 1.5)
squadron(1)
Its important to not touch anything on your screen while the sendkeys are running; after your in the Dungeon though your good.
It will run the whole Dungeon unsysnced solo.
