Grand Total on last page

Hello,

I have a tabular report with some data in the header of the rtf template. The data model is structured as follows:

G_1

    G_2

So, I have a for-each@section:G_1 construct so that the data elements in header update when data changes.

I also have a Grand Total field that should print on the last page only.

Instead, the Grant Total field prints whenever the section ends.

I tried adding a section page break and using the <?start@last-page:body?> <?end body?> tags and put the <?CS_1?> after these tags in the new page, but this does not work either (CS_1 prints at the end of each group break).
