This wouldn't work, because I have lots of different such times during the day
which cannot be grouped into 2-3 main categories.

4pm was only an example. It can be any other time during the day and I only
want those items to appear when their time is due.

It would be nice if org handled a category or something which I could add
to the task and it would affect its display on the agenda.
