'Z' to combine stacks of Currency on the floor

Late game looting can require significant numbers of clicks, Harbinger being an extreme example of this.

It would be a fantastic improvement if like currencies on the floor were able to be stacked by hiding and then showing all currency (i.e. press 'Z' twice).


A simple example in practice: there are 5 stacks of 3x currency A (with max stack size of 20) on the floor and 3 stacks of 5x currency B (with max stack size of 10) on the floor.
Player presses 'Z' twice, and Currency A combines into one stack of 15 and currency B combines into one stack of 10 and one stack of 5.

This would reduce the number of clicks to loot from 8 to 3 and also reduce screen clutter.

Thanks!
