"Projects for me" filter should apply to the user whose timesheet is being edited

When a user, such as a Personal Assistant, is in the 'Hours' section and submitting a timesheet on behalf of another person, the 'Projects for me' filter should display the projects assigned to the person for whom the timesheet is being filled out, rather than the projects of the assistant who is performing the action. This would make the feature more useful and efficient for administrative staff who manage timesheets for multiple users.
