(View) Column that displays a user based on the role they are assigned to within a project

It would be extremely helpful when displaying a group of projects to have the ability to create a custom view that adds a column that displays a user name based on the role they are assigned to within a project. Right now you are only able to display the owner of a project. It would go something like this:

Project>Task Role (Name)>User Name

It would also be helpful to be able to display a column showing dates associated with specific tasks. So if you're viewing a group a projects that all have a task called "Design" with a due date, it would display those due dates in that column.
