Receiver with subwoofer level buttons?

Yes, but those functions are done in the subwoofer plate amp. So, the remote would be controlling the sub not the receiver.

Everyone needs to make sub adjustments from the seating position. Please add level, phase, polarity, and freq cutoff buttons!

If this is strictly for HT being managed and run by a mass-market AVR I would’ve saved the considerable $$$ and bought the SVS sub(s) with their handy app and just avoided the issue altogether.  If this system is also for serious 2-channel listening with dedicated stereo components incorporated (and fully bypassing the AVR in that application) I totally get the JLLabs sub(s), but otherwise they strike me as not only inconvenient but probably also overkill for the application.  

@soix I have SVS subs and their app and i do love the app (except it won't link multiple subs together).

This system is for everything from kids Disney, to my youtube, youtube tv, to serious two channel listening/rocking so it's nice to have better control at my finger tips.

Many of the subs settings can be done via the HT processor/preamp, but we bury those settings deep within the menus and they're rarely used.  If they'd put buttons on the remote, we could utilize them more and make it MUCH more convenient.  Since MOST subwoofer manufactures have not offered remotes, this would be awesome.

It looks like Emotiva and Anthem are the best bets.
