Configurations in Assemblies and PDM Standard

We switched over to PDM Standard from Workgroups PDM last year and love it. I recently started creating configurations rather than having the same file repeated several times with only minor changes. O-rings and screws are some other items I've switched over to configurations so if there's a change in the o-ring size or screw length, this can be done easily without changing mates or explosions. The problem that I'm having with PDM is that it wants to overwrite the files every time they are used. I don't need to overwrite the file. I just want to use a configuration.

Is there something in the settings that I need to change?
