Levels in Table of Content

[Sunchaser]

Dear all,

I have a simple question ( may be quite simple ):
. in Report Studio, how can I have "levels" in the cognos table of contents ?
I mean something like:

1. Section 1 ....................... page 1
    1.1  Sub Section 1a ......... page 2
    1.2  Sub Section 1b ......... page 3
2. Section 2 ....................... page 4
    1.1  Sub Section 1a ......... page 5
Etc...

I'm sorry if it is written already somewhere in Cognos Docs, but I can't achieve this alone.


Thanks in advance,
Vinc.
