Positioning of Subreports in Crystal Reports

Hey. I have been creating Crystal Reports within Visual Studio and I always run into the same issue regarding the positioning of elements on each page of the report when using sub reports.

For example lets say one page makes use of 3 subreports. All three of these reports can expand based on the data passed to them.

I'll place the 3 subreports on the page.

If the subreport grows very large it will overlap the subreport below it. I was under the impression that the subreports would strecth and push the other elements below it.

Is there a way to position the subreports on the page such that they automatically push anything below them down on the page?
