Allow filtering by assignees in the releases overview

We manage several products at the same time

Each products has several releases.

Each member of our compagny is likely to work on several products.

In the releases overview, I would like to see the features assigned to a specific user to check if his tasks from a product do not overlapp with tasks from another product (and easily move a task id it's the case)

I can add filters to select products and releases that I want but filters "Feature assigned to user" or "Todo task assignee" are not available in this view.

I can create a specific custom view (Report \ custom) with specifics products, specifics releases and specifics users but I can't move feature in this view.
