Is it possible to use a Bluetooth Shortcut Remote in Artstudio Pro for iPad? There is a bluetooth gamepad called 8BitDo Zero that works in Clip Studio Paint. Clip Studio Paint lets you map keyboard shortcuts to each of the buttons.

I was hoping to use something like this and set up keyboard shortcuts for each of the buttons:
