Every Jira project has a list of project members, I want my assignee board to be able to be configured to just show those assignees or else there is just too many assignees diplayed on the board to be useful.

Even better, I'd like to be able to filter the assignee board by roles, so I can create various roles within assignees for "Designers", "QA", etc. and get an idea how those sub teams are allocated (not as important a request as the 1st one)
