Ctrl Click Inventory

Description:

Ctrl + Mouse click auto stacks the item to wherever we're moving it.
Reason for Suggestion:

Being able to ctr and click and have it auto stack to the same item in a container such as a duffle bag would just be convenient and save a lot of headaches and time. For example when dumpster diving I can control click on batteries and it stacks automatically with the batteries in my open duffle bag.
