I am looking for an addon, that if you are in a group with someone who is prospecting ore for you it keeps track of the amounts and types of gems and how many stacks that are prospected while grouped.

I typically ask jc'rs to prospect 15-20 stacks of 20 ore at a time and it is hard to keep track of how many gems they actually prospect compared to what they actually give back, since some times there are single gems  up to 3 gems from each 5 stack.

This could probably work for disenchanting items as well to keep track of the mats obtained.
