Sequential shifter for G920 + Xbox One?

[RikkiGT-R]

As titled, I notice the official shifter add-on for my wheel is H-pattern only, but some cars have more than 6 gears and I'd like a sequential shifter for certain cars anyway, for the sake of realism.
Does such a thing exist for this wheel?

You can mod it with elastic bands I believe. Or get a DriveHub + Thrustmaster or Fanatec shifter combination.
