I'm trying to make a field set to required for a single project, I've done this before for custom fields. I have made the project it's own field configuration scheme. It's associated to a screen. I think everything is set up correctly, or perhaps I'm skipping a step. 
So this global field "environment" associated to other projects, if I make it required, am I also making it required for other projects? I would like to prevent this from happening, I was under the impression that these fields are independent once a new Field Configuration Scheme is made (long story).
