I'd like to know if this is possible.

Let's say I have 10x Spirit Dust in the crafting queue. If I try to move items under the Crafting/Enchanting group from the bank to bags, it moves 10x Spirit Dusts to my bags regardless what's already inside the bags. So if I already had 10 of them, addon transfers another 10 and now I have 20 of them in my bags. Is there any way to prevent this?
