I feel like this question is awkwardly asked, so it might be obvious and I just don't know how to ask it properly.  That being said, I would like to make my default option when editing a dimension to apply only to the active configuration rather than to all configurations.  I have been bit by hitting enter a little too soon and not noticing and having all my configurations all messed up, and it is super annoying.

How can I change this?

Thanks.
