I've made a new "Create Issue" screen that I want to use for all "Bug" tickets in Project A. (I want Project B to use the Default screen when creating new issues.)
I have...
- created and configured the Screen (e.g. "NewBugScreen")
- created a Screen Scheme ("CreateBugScreenScheme")
- created an Issue Type Screen Scheme ("Create Bug") (and associated this with CreateBugScreenScheme, from step2)
- opened Project A admin, Screens tab...
It is in step 4 that I start to lose my way. At one point, I somehow set it up so Project A uses my NewBugScreen for all new Bugs -- but now all my other projects use the NewBugScreen too, which I don't want! I can't seem to figure out how to associate the "Create Bug" Issue Type Screen Scheme exclusively with Project A.
(The screenshot below demonstrates exactly what I'm trying to do.)

Neither the "Configure" nor "Edit" links take you to a screen that allow you to associate a project. (Which is why, in step #4 above, I tried to do it from the Project admin screen. But if the path is there, I couldn't find it.
