BT, I've been running to FOH and stage FRFR for pretty much all of my Axe Fx time (coming up on 2 years now), using the method Simeon outlined. I use Out 1 for FOH and Out 2 for my stage monitor, set as Sim noted above. It works perfectly; I can send FOH a level to set my mixer channel gain by (which needs to not move thereafter) and have a volume knob to independently adjust my stage monitor without having to get on my hands and knees to find the monitor's own volume knob.
If you don't need both sends from Output 2 for another purpose, this is the fastest and easiest way to get the Outputs you're referring to here. It's a proven method, and works on the Ultra or II (and probably on the Standard, though I haven't personally owned one). Hope that helps!
