[Orgmode] Format of headings spanning days in agenda day/week view

[Nick Bell]

At present they look like this:

        (1/2):  John's Event <2009-09-03 Thu>--<2009-09-04 Fri>

I would rather the <2009-09-03 Thu>--<2009-09-04 Fri> was missed off 
entirely as it's obvious from the agenda when the dates are.

Also, I'm using custom time formats which these events spanning days 
don't seem to take with them to agenda views (but as I said I'd rather 
the days/times were missed off entirely)

Is there any way of doing this?

Thanks

Nick
