Conditional page breaks

I want to set a page break at the change of a group conditionally based on a
parameter value. Is there any way to do this in Reporting Services?Any help here? Because I would *really* like to figure out how to do this.
Once again, I have a grouped table in a report layout. I would like to have
a page break at the end of a grouping happen conditionally based on a boolean
parameter that I pass to the report.
