Although this suggestion is indeed good, at least 2.9 is better than 2.86, AhBeeDoi. Once you choose quick action for a loadout in-game, it will remain the same as long as you don't change it, even if the item selected, say, grenades, is depleted.
What i suggest is to take the time to launch an offline match with lots of livesand short respawn times, then go through all your loadouts by selecting the QA item/typing "suicide" in the console...rinse, repeat until your QA is set for all loadouts, and voilà, you should never have to change your QA at the beginning of a game again.
