I have not found this to be true. CYA will not just dissolve quickly even in warm water. It will still take awhile. Don't worry about it. Just pour it in through the skimmer while the pump is running. Then, don't test for it, backwash or add more for about a week to be sure you give it time for all of it to dissolve. It is better to add it gradually and sneak up on your target rather than try and hit it in one dose. Be patient and you can get the level where you want it to be.

That's in the quote from the "WATER CHEMISTRY FOR SWIMMING POOLS". I actually have always used the panty hose method, and have never tried dissolving it in warm water . . .
