How to pull candidate source per application/submission via REST API

Summary:

Hi All,

Currently to my understanding, when pulling the candidate source via REST API it returns only the first source that the candidate used. We are looking to see if there is a way to pull the source for a candidate per application or submission.

I.e. If I apply to a job posting through Linkedin, my candidate source when pulling from the candidate information provides Linkedin. If I then, as the same candidate, apply to another job later through Indeed the candidate sourcing still lists Linkedin.

Is there a proper way to pull/query the candidate sourcing information more granularly? Thanks in advance!
