You're a godsend bro. Thank you.
Currently, what I do is:
1) input the MTIVRNG into Researcher
2) set the Frames to 1-3500 (3500=500 Box/Party Drag & Drops which isn't terrible)
3) output the Results to CSV (Excell)
4) delete the unnecessary columns
5) Ctrl+F to Replace all "31s" with Bolded, Underlined, Highlighted "31s" so I can see them better
6) Scroll really quickly down the page till I see a 31, then look at the 5 cells above it
If it's any good, I write its location down. If not, I scroll on. It's pretty tedious though.
