Kanban board filter options

[#1]

On the Teams Kanban board filter functionality, where a user can filter by placing a check in the checkbox field next to a name of person on the team. There only ability is to check "unassigned" or by checking or unchecking the names one by one. Can we have the functionality to check "all" or uncheck "al"l team members in the filter. If you have a big team it can ages to check or uncheck users.
