I'm just finishing a report that uses two paramaters--a date range and a static pick list.  The date range parameter is used to filter records, and the pick list is used to conditionally suppress sections.

 

So, is it possible to set multi-value defaults for these parameters?  For the date range, this means having different default start and end dates; for the pick list, it means having multiple default values.

 

I've tried to accompish this by including the multiple values in the default value field in Edit Parameter (e.g. "7/1/2007-6/30/2008" for the date range and "Address;History;Actions" for the pick list), but no matter what syntax I use it doesn't seem to work.  For the date range, the default value field is cleared as soon as I tab or click out unless I enter a valid, single date.  For the pick list, the entire string I enter is included as a single default value when the report is run.

 

Any ideas?  Do I not have the correct syntax for the default value field, or is this impossible to do?
