Yup. If you want to practice just everything after a break, make a separate difficulty and delete everything but the part you want to practice. You then have two options:
1. Edit the map to put a silenced 1/32 repeat slider a few seconds before the map starts. This gives you a "natural" 200 combo flashlight, where it fades back to 0 combo if you break.
2. Use a special cursor that mimics 200 combo flashlight. This won't fade away if you break your combo, helping you memorize better, but it isn't 100% accurate since Flashlight doesn't follow your cursor 1:1 (and also I don't think there are any cursors out there that are exactly like the FL ingame)
Lots of good flashlight players use one of these tactics, and it really does help. I never would have been able to set
these scores without practice difficulties.
