Assesment can be graded by any instructor

Hi,

There are several problems with assessment feature in coursepress.

1. After selecting a particular course in assessment drop down menu, It list all registered students to all courses rather than displaying the students who registered to that particular course only.

2. Assessments in other courses can be accessed and graded by any instructor. These assessments should be only accessible to instructors to a particular course only.

3. Assesment course selection drop down menu display all courses rather than once relevant to a particular instructor.

Please include instructor capabilities for assessment to control visibility.

Can someone please look into these issues with assessments?
Thanks.
