You used to be able to do this with scrips. I used one to do mass turn-ins of thorium bother rep. No idea if it still works though.

Deadly boss mods has auto turnins for AVs once you click on the NPC so it might be possible for other quests, you'd just have to click the npc and possibly pick your reward when needed. Saves a few clicks at least, but would probably have to be customized for every quest.
