We use InTuition to track client roles as well as our own, and they have many that have prerequisite job roles. It may only have one, or it could offer a handful of relevant prerequisites.

Can something be added to denote this need and a way to identify the required role.

A drop-down or a blank field would be enough, with an option to have the information shown in the search. Even just somewhere that notes/comments can be made would help.
