probably possible but we need to know what ECM/mask you're using each time you ask questions like this

ahhh my bad, I thought had uploaded the photo. .

The ecm is the 1227747.
The mask is $42.
The BCC is AHWZ.
Yes, it's possible to program the ecm to increase idle speed if it appears the A/C is engaged.Is it possible to program the chip to increase the "AC" idle to let's say 950 rpm's?
This is good news! What would be the easiest and most affordable way to accomplish this? I'm an old Carburetor Wrencher, I was able to figure out how to install TunerPro RT and get the ecu to throw live data to my laptop, this is new territory for me.
thanks again!

The easiest way is to pay someone else.
Affordable will depend on how many additional changes you may want as time passes. If you invest in the tools then you can make your own changes whenever you'd like.
Good point. This is for a custom off road use only vehicle. 5 mph average, possible up to 20 mph. It sits at idle 80% of the time it's being use turning two high output Alternators, which is why I'm looking to manually bump the idle. I won't be doing much in the way of programming besides bumping the AC Idle switch. Would love to program it to increase AC Switch idle to 950-1000 rpm with the flip of the switch.
What would I be looking at to have someone program it for me.
i had a peek and there are already added steps for when a/c is engaged in your stock calibration (so it doesn't stall out from the load), but then the 'idle target' isn't increased so it would settle back to stock idle target.
your stock idle target is 600, here's a bin with the idle target 300 more rpm when it thinks a/c is on
now you just need to get some programming gear together so you can modify your chip and throw it on there, recommend stuff from moates.net i guess
attached xdf and the bin, load both in tunerpro and make further changes if you want
