Can't you hotkey the 2 daggers?
Nope. What you can do, is bind dagger 1 to "1", dagger 2 to "2". When you press "1", your char should automatically take the second dagger in the off-hand. But this only works as long as you dont use any spell. You will have to reconfigure after that. At least that's the only way I managed. Kinda svcks...
