I would like to be able to set the timestamp of some headers to an interval of time interpreted as 'or'.
For example, I would like to be able to assign a todo item at some point next month, but I don't want to specify a date yet nor I want the item to appear as todo on every day of next month (as would happen if I set the timestamp to an interval). If I set an interval to be, say, Monday to Wednesday next week, I would like it to be interpreted as Monday or Tuesday or Wednesday.
I have tried to just have a different file for headers that are to be interpreted in this way, but it is not ideal.
