The function of the preset list is to provide a list of all props, costume pieces, and set pieces that should be prepared on each side of the stage, props tables, and any other locations before the show.
There should be checkmarks for each run, tech rehearsal, or performance so you can always check off that everything is there. This will be printed and kept with the SM or ASMs in charge of presets. You will need to reset the major things at the end of each show as well.
I recommend formatting this sheet by area and with checkmarks for each run, as you can see in the example.
