What I do for multiples higher than ten is to repeatedly click the mouse key. For 83 cards, I would indicate 10 cards, and repeatedly click the mouse key before it totally accepts your entry, (so, i would click it 8 times), then add the 3 after the 80 loads. For an entry of 24, I would enter 8 and hit the mouse button 3 times. Seems to work for me. I had suggested some way to just show how many cards you had, For example Fred Smith 83. Others liked the fact you can list a grade for each card. So, it has both arguments.
