Yes it is. What I do is download all of my matches and my sisters in one hit and my father's. Then I copy the results onto one spreadsheet and work out which ones we have in common with him so the rest are maternal Cornwall or Scotland. I do the same for GEDmatch every day and I've started on MH. I have my mother's matches on a spreadsheet with over 15,000 matches - albeit several duplicates.
You're there

. And yes, I need to get a life.
