Project Dashboard – Filter saved search

If you wanted to filter a sublist on a project record you could just add the project as an available filter on the saved search and it will automatically filter the results to only records associated with that project.  I’m trying to accomplish the same thing with the saved search on the project dashboard but the results do not filter.  It is like the saved search on the project dashboard doesn’t recognize that it is on a project.  Any suggestions on a filter, formula or other work around?
