for any given node choose between repeating or multiple dates

It would be really great if the date widget could be set up in such a way that the user (or whoever is actually inputting the nodes) could choose for each node whether to set up a repeating pattern, or to input individual multiple dates.

Right now, if it's set for a repeating pattern, someone inputting an event that happens on January 1, January 6, and January 7 needs to say the event is happening daily between those dates, then exclude January 2-5, which requires submitting the form for each exclusion.

Alternatively, if it's set to input multiple dates, someone who is inputting an event that happens every Saturday for 6 months needs to add 24 separate dates, something which also requires multiple submissions of the form.

For both of these cases, adding dates is a cumbersome, user-unfriendly process. Allowing the user to pick which date type is most appropriate for their particular event would greatly enhance the usability of the form.
