Theme Builder

Hello,
This is a newbie question and I am hoping for some suggestions. I am setting up a forums space using the Theme Builder 4.0.2 and have structured the space in the following hierarchy

• Level 1 - Forums Summary: this provides summary of all the individual forums created in level 2
  • Level 2 - Individual Forum; this is the individual forum area
    • Level 3 - Individual Topic for Individual forum

In the navigation section of the theme builder, I would like setup additional menus that only show at Level 3 (i.e. at the topic level) in the View mode. These menus will contain items like  Set Sticky, Edit page, remove page etc. I am planning on using the Builder -show macro with the compound menu item macro. As the individual topics are a child of the forum, my question - is there a way to identify whether the page is a child page of a forum, so that I can then show the menu items to the child pages only.

Any help will be greatly appreciated !

Thanks
