Mirroring with configurations

Hopefully this is just me not finding a tick box.

This has cropped up in the past and again this morning to a colleague. Is it possible that once you have done a mirror that contains configurations, that you can then add another configuration to the original part and it gives you the new configuration in the mirror that's just been created. The mirror doesn't seem to up date with the newly created configuration.

Thanks

Steve
