[Koha] Cataloguing Items with Multiple Parts

Hi All, I'm cataloguing an item with multiple books as part of the package. Ideally, I want to catalogue each individual book in the package and then link those Bibliographic records to a 'main' Bibliographic record for the kit/package? I used to be able to easily do this in our old ILS, but still haven't come up with a way to achieve this in Koha. Does anyone have any suggestions??
