There is something I want to do on Monday, Wednesday and Friday. So I tried:
*** TODO Monday, Wednesday and Friday
    SCHEDULED: <%%(memq (calendar-day-of-week date) '(1 3 5))>

This seems to work: I see the activity on the correct days.

But then I changed today's entry to DONE. But then all are gone in my agenda view.

What I want is for today's item to be 'gone' and the future ones still displayed as TODO. Is that possible?
