I should also mention you will want to use a very clean profile and turn off any FX, Cab/IR, etc. That should give you the best shot at getting the right curves for the Amp EQ sections.
Also note the liquid EQs may be interactive so you cant sweep the mid for example and call it a day. Adjusting the bass/treb/pres may affect the mid freq and response.
REW is great for making profiles as well. You can sweep your mic setup and see if you have phase issues like suck outs, echoes cancellation, etc. First time I swept my 2x12 cab I was blown away by how much the one speaker bled into the other. I ended up piling deadening material around the unused speaker.
Best of luck and have fun.
