Tash - items on a worklist are displayed in 'oldest at the top', 'newest at the bottom' order - ie the one that started longest ago will be at the top.

If you add a new entry and back date it's Start date, then it will not be at the bottom of the list.

I suspect that the way to handle things is (assuming that you only have one puppy class per day) is to remember that you can 'forward book' an entry in the work list.  That is if the start date is in the future, it will not show until that date. Also if you set the end day to the same (future) date, then it will only show on that date.

We can now look at the puppy class work list for next Tuesday and see how many we have booked in.

If you have a morning and an afternoon class, I would have two worklists, one for the morning session and one for the afternoon.
