Is it possible? I seem to only be able to add single spells/weapons, not combinations, to the favorites. I'd like to have a bind to switch to just a 1h weapon without it keeping whatever spell I have equipped, so that I can block. Also would be nice since I've taken the dual casting for destruction, to not have to hit a button twice to equip both hands.

Bumping 'cause this is hands down my biggest issue with the game so far.
It is so horribly awkward without this I've given up blocking with 1handed weapons entirely, 'cause it always keeps the off hand spell equipped. There's no convenient way to clear it.
Just needs to be made possible to fully enjoy the game, seems like a pretty incredible oversight to me that there is no way to do this considering how much emphasis they put on this dual wielding system.
