Dungeons reset after a brief period of time, so that can't be done.
Overland Quests can be banked to turn in all at once. You can also do Master Writs, people like Alchemy, Provisioning and Enchanting for that. Make the stuff before you accept the writs, then stand in front of the vendor accepting them and turning them in.
But the most reliable way is to find a nice quiet grind spot, pop the scroll and go to town on the mobs. If you can find someone to do Skyreach with you, that can be good too.
