Get all the drops you're farming from whether it be Mana Golem or something else . get all the drops and then disable get all drops when you have it all and when you get new items it should only be the one that you're looking for . Ex : Voucher of nulgath so when you get back to check on it , only the voucher will show cause that's the only thing you haven't gotten so therefore you can just click yes to get it manually and this makes it so the only drop to show up on screen would be the item you're farming for. so you can just pick it up manually and not d/c. well that's what i do anyways.
