I'm new to Jira so be gentle 
I was hoping to use Jira for issue tracking in a very special way. I found that as a Admin I can create Issues with custom fields, but can I make those fields have data validation that changes based on the project?
example might help. We do audit work with several customers - each customer has pre-defined scenarios - I'd like to quickly create an issue that includes what scenario it is targeting. Customer A's issue creation should only show Customer A's scenarios as options, when working on Customer B's audit the issue creation should only show Customer B's scenarios... but in both cases issues should have a required custom field for Scenario.
