How to track candidates who has used LinkedIn profile import option

Summary:

Hi,

We have enabled LinkedIn Profile import integration in ORC for our client. But not able to track who has used that option while applying for a job requisition. I have checked in OTBI reports area, but not get anything familiar to this. Also checked the Source of the application, not it is saying that candidate has applied through external career site.

So is there any way to monitor candidates who has used LinkedIn profile import option while apply for a job on career site ?
