Passing Parameters to Bookmarks

Hi!

I have this situation:

1. I start on Page "A".
2. I travel from Page "A" to Page "B" by drillthrough, passing 1 parameter.
3. From Page "B", I want to go to Page "C" (pressing a button, calling a Bookmark).
4. I would like to mantain that parameter in Page "C", but actually this is not possible.

Is there any workaround to simulate this?

TY!

Regards :)
