I would like to set the assignee to an individual that would not have access to JIRA. This individual would be a person at a third party vendor.
I am primarily looking to do this as we work on projects and issues arise, we create an issue ticket and link it to the parent project.
I would then assign the issue to the vendor company and the individual at that company that will be working on the issue.
This would give me reportability of all open issues for a project that is being handled with a vendor.
