Include page list for navigation

I've got a VERY simply Dashboard that consists of 5 SSRS reports. The user navigates among the reports using either drill-through functionality from SSRS itself or by using the breadcrumbs at the top of the dashboard. I am wanting to hide one particular report from the breadcrumb section, though. I only want my users to access that one via drill-through from another report. How can I accomplish this? When I'm in Dashboard Designer, the "Include page list for navigation" option in Deployment Properties appears to be an "all-or-nothing" option. I can't un-check it for one report versus another. Help, please!
