It's not for a special challenge, it's of general interest for me. I know the D/T Matrix tool is going into the right direction, but as you only can select D and T separately, I would receive to many results. Let's take the example D/T 1/1, 2/2, 3/3, 4/4 and 5/5. If I want to get a query for this 5 combinations, I had to select D 1, 2, 3, 4 and 5. For T the same. So I would also get combinations like 1/2, 3/5 or 4/2 in the results, which I don't want.
