We have about 12 users on our team. JIRA issues are first assigned to our team id. Then individual team members click the "assign to me" link to take ownership of the ticket and work the ticket until closed. The issue I have is that sometimes other team members within a few seconds accidentally assign the same issue to themselves that I've already assigned to myself because they have a stale view of the ticket assignee. I also try to prevent taking tickets that other team members that have already assigned to themselves by reloading the JIRA page multiple times as a workaround (very tedious). Any way to create a rule that a ticket cannot change ownership more than once per minute, etc? Most code repositories have a way to checkout or lock a resource. Hoping there is a way to do this in JIRA.
