How to clear prompt values in Analysis Studio

[mrcool]

Hi All,

I have mandatory date range prompt in one of my query subject. When I drag a query item from that  QS I am being prompted to select the dates.
Here is the actual problem, I am unable to clear those prompt values to select new values.
Is there any way to handle this scenario?

Thanks in advance,

mc
