Taleo Candidate merge/update script

Summary:

Hello Sir/Madam,

Field name: Credentials,SSOID

1. Can we make the above a searchable field on the Candidate merge/update scripts in TCC and so that the script can search and update a candidate profile in Taleo, using their SSOID.
2. Or, is this field available in another field path, as a searchable field, on the candidate merge/update script in TCC.
Kindly help us with this.
