Filter Option

Under "Reported By", "Assignee", and possibly "Project", it would be nice to be able to either have a "not" operator as part of the drop down list box (ie. not Current User), or be able to select multiples (preferably the "not" operator for "Reported By" and "Assignee".) I want to create a filter for all issues where "Reported By" = Current User and "Assignee" <> Current User. This would allow me to keep track of the issues I have created for projects that are not mine.
