Is your feature request related to a problem? Please describe

Hello,
When you are on a project, you can filter tasks by user, but you can't choose to see the tasks that are not assigned, or select your tasks and the ones that are not assigned at the same time.

Describe the solution you'd like

Being able to filter not assigned tasks, and perhaps also my tasks at the same time, but not other users tasks.
