Filter Sream view by dates or assignee

The Stream view is useful to trace back comments but also changes in tasks (autoupdates). It would be great to be able to filter a Stream view by date or by assignee.

An example: if someone modifies a work schedule with unavailable dates, many tasks assigned to this person will get rescheduled in different projects. The idea is that by checking the Stream view using filters, it will be easy to identify these tasks. 

It is a real case I've struggled with.
