I apologize if this question has already been answered but I could not find a related question...
Our engineering organization uses a Scrum Team structure. We have adopted a JIRA process where the Assignee must be a real-life/breathing human. However when running a single JIRA query, our managers would like to sort Open Bugs (for example) based on team...not by individual assignee. What we have done in the past is have a custom "Responsible Team" field that was independent from assignee. That is, if a bug got re-assigned to another engineer in a different scrum team, people would very often fail to update the "Responsible Team" field. Instead, we would like the "Responsible Team" aka Group Picker field be automatically updated by the Assignee (i.e. by leveraging JIRA's Users and Groups).
So my question is, can one create a custom group picker field that automatically gets updated based on a the assignee field?
