I have to create a required custom field to force developers to supply specific information before sending a ticket to code review. I want that field to be shown on only two transition screens, and I want to share those two transition screens across five projects. The field is not supposed to be accessible on a "create issue" screen. I had someone attempt to create an issue and he was not allowed to continue because Jira required him to fill in the custom field, which wasn't shown on the create issue screen. Is it possible to use required custom fields selectively on screens and across projects?
