Record for pulling the Service Provider Name in Template Variables - WO Submittal Notification email

We are modifying the Work Order Submittal Notification email to include the Service Provider Details( Service Provider ID & Name). Hence, we have added the WO_CONID from SPF_WORDERREC Record(for Service Provider ID) in the Template Variable ID - SPF_WORK_ORDER_CMP.

For adding the Service Provider Name, if we use NAME field from the SPB_PERSON_TBL, it was pulling the Provider Contact Name(instead of service provider) as both of them share the same related display record at WO component level.

I think I need to pull the service provider name from another record in the template variables.  Would you happen to know where I should be pulling it from. I tried changing the record to SPF_TASK_WRK but it's not pulling in any name in the WO Submittal Notification email.
