Under the Default Field Values of a Job Nimbus user profile, can we please have 'Job - Lead Source' as a Default?

Use Case: In the field I have ambassadors taking leads by putting jobs straight into the CRM. with appointment dates.
Job - Lead Source - would need to default to that entire team as "events" as a source we use for all field booked appointments.

Would like the same drop down list of "Contact - Lead Source" to be Job - Lead Source as our field team builds a job with appointment, that the Contact Center then sets up a contact to marry.

Thanks,
