Option to add new tasks to the bottom of a Time Slot (not the top)

Right now, when I add tasks to a Time Slot, new tasks get added to the top of the list. I usually type tasks in the order I want to do them, so they end up in reverse order and I have to manually rearrange them every time. It would help to have an option to add new tasks to the bottom of the list instead (or a setting to choose the insertion order), so they stay in the order I typed them.
