The pill container was a great idea to soak them all at once. I usually only plant moonflowers now, so those I just toss them in any glass overnight next to a heat vent after nicking them, so there's no need to keep track like you did.
But once I plant the seeds is different. I made sheets of all my seed starting containers on my computer, they each have from 36 to 72 spaces. Then print out the blanks and fill them in as I'm planting. There's no way I'd stay sane trying to put over 200 sticks in the cells. I often make notes on those sheet about the seeds. Then I scan the sheets and save them per year so I always know what I planted and what worked well from one year to the next.
