Allow increments of 1 for the round limit for "Duel" mode in Parties. A friend and I wanted to practice for an NMPZ tournament and I decided to create a party and simulate the rules of the tourney, but as it turns out I can't select 7 round limit if the mode is "Duels". It's only 5 or 10, which is not ideal if we want the exact same format. I think it would be easy and beneficial if we could select the exact round limit, not in increments of 5.
