Is there a way to update the LOV's that populates the 'Source' field on the Talent Profile?

Summary:

On the Talent Profile, there's a field labeled 'Source' on most sections that is used to identify where certain information came from. We're looking for where that LOV's behind that 'Source' field is kept. Is there a way to add / edit the values in this list?

Content (required):

We have a new hire who's Talent Profile information was populated by a background check via Recruiting. However, when you look at the 'Source' on this persons Talent Profile, it just says 'Talent Profile,' even though it technically came from Recruiting. Is there a way to update / edit the list and the mapping for this field so that it can be more accurate when displayed on the Talent Profile?
