I pretty unfamiliar with crystal reports. Can crystal reports be used to configure report fields dynamically?

My company wants to allow users to select, from a list, database fields they want to see on a report. They will also have the ability to determine selection criteria.

I'm not concerned about the selection criteria aspect of this. I've looked into Crystal and seen a few examples using datasets, so the selection criteria can be handled in the dataset creation/fill.

However, I haven't seen any tools with Crystal that appear to allow a report to be dynamically created/modified (add specified database fields to the report). It seems that all reports are created as static files, as far as the displayed data is concerned.

My boss seems to think this can be accomplished using crystal. Am I missing something?
