We have a JIRA instance with 20 schemas and wide field usage of date fields. We would like to "get the genie back in the bottle" so to speak and set some definitions around common fields to be used. For example, we don't need a dozen due date fields, maybe one or two will suffice. The issue seems to be that we have allowed too much customization and also may no longer be aware of what we can do as JIRA admins to create a more consistent experience and get people to populate common date fields. In other applications, I have seen people admin with the approach of a base set of expectations and then allow customization on top of that. Is that a potential option with JIRA Cloud? If yes, what are some best practices to achieve it?
