APEX

We have an interactive report that is filtered, sorted, etc by the user to get the exact set of data that they need to download.

We need to download only certain columns of the report.
We don't want the users to have to hide columns.
I'm looking for something like the "include in export" that can be specified for each column in a standard report.
I don't see a place to set that in an interactive report.

Is there a setting that I've missed?
If not, any suggestions for possible solutions would be appreciated.

thanks
