[Koha] How to define that library loan X copies are only for students enrolled in the X Library school.

Good afternoon, Considering Koha in a Bible Network. How to define that library loan X copies are only for students enrolled in the X Library school. When selecting a student enrolled in a Library the system is allowing to borrow from copies registered in other libraries that the student is not linked. How can I solve this?
