It's not a FAQ but the answer is easy:
Each ranked CTTH round is an unlimited tourney round (monthly sweepstakes), and unlimited stroke play is Tournament, too. In these tournaments you have the "Restart" option, in regular single (=alone) stroke play you have not.
So, if you wanna grind something out, you might want to create an unlimited CC tournament or look out if one of the weeklies/monthlies fits to your wishes.
(e.g. chasing birds on BPB #15 works well with Best of Hardest front nine - it's the first hole there)
Have fun!
