Quikset compound
Is there anything I can add to the mix of quickset joint compound to slow the set down just a bit. Like maybe 15 0r 20 minutes on a quickbond 90.

Look for a different product that has the working time you need.
Quick Bond 90 is a two part epoxy generally applied using the supplied two tube applicator that mixes the product so there is no chance for you to mix in anything else. It has a super fast kick rate and is only workable for about 90 seconds so there isn't a snowball's chance of extending it to 15-20 minutes. Heck, that's even beyond it's ready to sand time. You can refrigerate the epoxy to slow slow the cure but it will never buy the 15-20 minutes you want.

Oh, sheetrock mud... very different.
Mud dries by evaporation. Think of it as plain old mud with some white glue mixed in. If you want to extend the drying time then lower the temperature, turn off all fans and close the windows and run a humidifier to keep the air more humid. You can also use a spray bottle or mister to keep it moist until you are ready.

If Olderdude is talking about a setting compound, like Durabond 90 or Easy Sand 90, they don't evaporate, they set. It's a chemical reaction. The only way to slow down that chemical reaction is to use a retarder, lower the temperature, or both.

Some guys will mix a little ordinary joint compound in with their hot mud, to delay the set time. One well known tip is that mixing hot mud in a dirty pan will make it set up more quickly. So if you aren't cleaning your pans out, and you are mixing in a dirty pan or with dirty water, that could be subtracting some of your working time.

How much more time do you need than 90 minutes? Plan your work to do what you can do within the setting time. Then mix another batch and continue. What has been said about clean equipment and clean water is important.
If you can find some retarder be careful . A little gone a long way. A little on the tip of a screw driver will retard a mud pan full maybe to the point that you wonder if it will ever set. Add the retarder to your mixing water then mix it. Retarder might be hard to find in some markets. I have heard but never tried i it that gelatin will slow the set of plaster. I have heard that sugar will slow it down. Alum will hurry it up. I think the chemistry of quick set mud is similar to plaster. Experiment with what you have at hand and maybe it will work.
