The ability to create prerequisite rules using either subgrid 1 or subgrid 2 of the subject.
Currently enabled subjects with multiple subgrids, only the subgrid 1 subject is available to create prerequisite rules with.
Currently Corequisite and Restrictions can only be made from the semester 1 of the subject, eg select semester 1 and get semester 2, but if you only select semester 2 you can't create a corequisite to get semester 1.
*****The new subject rules page will cater for corequisites & restrictions with the bi-directional setting. But ideally it would be best if the user could select either the semester 1 or semester 2 to create subject rules from.
