How to print another report from report script or extension?

Hi,

There is a standard session that I do not have the source code.
When a user prints from that session, there will be a list of reports to select.
When a specific report is selected to print, it must automatically print another report with it using the same set of data that the selected report is printed.
Is it possible?

I have tried
- brp.open()
- spool.open()
- AFS
for both the report script, session extension, and report extension.
None of them works.

Regards,
Thana
