You can use the retimer option of each tyFlow to essentially warm-start any flow at a given frame.
So, for example, if you go to frame 0 of your scene and set the retimer frame to 100, it will calculate up to frame 100 (in the sim) on frame 0 (of the scene). Each flow can have different retimer settings so each flow can be forced to evaluate up to a given simulation frame, for any given scene frame.
