ePortfolio - Modify Report - How to Make Look Good

[Hypermommy]

In the ePortfolio sample that comes with CR Enterprise edition, the end user has the ability to modify a report. They can, among other things, add fields to display on the report. If they add a field, however, it throws all of the other fields we've included on the report off. Data is no longer in the column it is supposed to be. Data is not formatted the way it should be (width, etc.). And the data that is included is not made to look good in any way. What kind of control do I have over the data that users add in this manner? Is there some way I can make all of this added data appear on another line or something, maybe just below each detail item?

Thanks.
