Is it possible to customize order routing in IB's mobile app?

Before I spend an hour on hold with IB to answer this simple question, figured I would ask on here.

Seems like there's no way to choose from direct or SMART routing with IB's mobile app - they only allow SMART routing. I can't even customize the SMART routing like I can on the desktop version to maximize fills or maximize rebates. Am I missing something? Seems like a glaring flaw that I'm surprised hasn't been addressed.

 

I don't think so, but it's been a while since I traded via the mobile app instead of TWS.
