Output routing question

[boynigel]

On my XL i have my guitar's magnetic pickup with its own chain, along with its piezo having its own chain.  i've got the magnetic pickups going out of the xlr output (L, as i'm running mono), and my piezo's output is going out of effects loop Send 3.

 

now i want to add a vocal mic but when i go to select its output, my only options, at least the ones i'd like to use, are xlr or effects Send 3/4.  would it be possible to run my guitar out of the L XLR, and the mic out of the R XLR?  the options i'm presented with are "XLR" or "Send 3-4".  i'm not seeing any way to specify L or R in the case of XLR, and the same with Effects Send-  there's no seprate output listed for 3 or 4 by themselves...only as a pair.  hopefully i'm just missing something here?

OP here.  in the absence of any responses, i figured out a fix on my own.  i'm posting this in case anyone finds themself in the same postion.

 

Here's what ultimately became the goal: To have my guitar's magnetic pickups and piezo pickup each have their own xlr output, and then a separate output for my mic which i (at least for now) assigned to the headphone output jack (assigning it to an effects loop Send jack was also an option but i preferred to leave those jacks available.

 

The first step was to have my outputs set up so they're not going through the default Matrix mixer.    this entailed assigning both the magnetic and piezo pickups to "Direct xlr" output selections.  then i panned my magnetic pickups hard L, and the piezo pick hard R.  adjusted their levels to taste in terms of their balance with each other, and that was it.  so now my xlr L Out is dedicated to my magnetic pickups, and the xlr R Out is dedicated to the piezo pickup.  

 

then i simply routed my vocal mic to the Headphone Out jack.  

 

the cool thing about having the two xlr signals balanced within the Stadium internally, is that i can then just tell the sound guy to keep those two faders on his board always at the same value as the other, ensuring i'll always have the balance i want between the two.
