Installshield LE includes my GAC files from the main output project, even if Copy Local is false explicitly

My problem is with one simple application project and a class library project with some GAC links that I add to the Files section (the primary output is only in the application project). The problem is that the REALLY installer wants to add all files that are not connected to the GAC network from the project to the installer, even if they are explicitly set to Copy local false (false in the project file).

How to tell InstallShield only dependency files that have Copy Local, and not everything in the list?
