Suppressing Features in Mirrored Parts

I am trying to suppress a feature on a mirrored part. I inserted the attached part into an assembly then mirrored it creating a new part that is linked to the original. I would like to suppress the boss on in the mirrored part? Or can I specify a diffrent configuration for the mirrored part, one that has the boss already suppressed?

Thanks,

Mark
