MainStage:What is the difference between Concert Level, Set Level and Patch Level?

I'm trying to treat the lead vocal on a gig with the same effects that I used on the record.

I have an input Channel with the vocal mic coming in.

I send a 2 busses from it. One is to an Aux channel with a reverb on it, the other is to an Aux channel with various other fx on it.

I would like to set the sound up and be able to save and recall using Patches EITHER the Buss level from the input channel OR the Fader volume of the Aux channel faders. I cannot get either methods to work.

Am I missing something?

Are Aux channels able to be saved as part of a Patch.

My set up is quite basic, I would just like to save and recall the different levels of the mic to these two channel strips of FX (or the levels from the output of the fx, whichever way works).

Thanks.
