RS reserving space onpage for hidden data

I have a report that has detail and a group. I have it set to hide the detail
and toggle on the group.
When the report first renders, I get the six groups spread over 3 pages.
That is 2 lines per page. When I toggle the hidden data, the result still
only takes up 3 pages.
How can I get the groups to appear on one page and have the report expand as
needed?Set the row hight, for the hidden detail, to zero.
There will still be some empty space but I find it acceptable
