Filter users by more than one group

The current functionality of Moodle allows a teacher to filter student's submissions, grades, etc. by one group if visible or separate groups is configured at course or activity level.

It'll be nice to have a way to filter submissions / grades / etc. by one or more groups.

For example, imagine a course with groups A, B, C and D and a task configured with separate or visible groups. A teacher is responsible of students at groups A, B and D. He/She wants to see submissions by all of its groups without having to visit group A, then B and finally D.

Thanks in advance.
