Trigger different background check packages for internal vs external candidates

Customer has a background check integration with Skill Survey for reference checks. They have 9 packages with the vendor and are coming off of Infor into ORC. The customer requires 1 reference for internal applicants (for all packages), and 3-5 for external applicants depending on the package.

Currently the set up in Infor is a recruiter creates a requisition with one Skill Survey package, and Skill Survey is able to send the correct reference request to the candidate based on whether they are internal or external. There is no set up for me to differentiate in ORC. In reviewing the 24D Background Check Partner Integration, I can't find any logic on the payload for candidate type.
