Write Multiple Records in One Write Records Node

Hi all,

May I please ask for some guidance here?

I've got three record types:

• Consultant (a person, e.g. an Appian developer)
• Consultant Certification (certifications the consultant has, e.g. Appian Associate Developer)
• Consultant Audit History (audit log of changes to various parts of the consultant profile and related record types, e.g. updated a certification's expiration date)

docs.appian advised against using Record Events to track changes to an individual record field (e.g. certification expiration date), so I created the Consultant Audit History record type. When the certification expiration date field gets updated, I want to add a row to both the Consultant Certification table and the Consultant Audit History table. 

To ensure data accuracy, I want to write both records at the same. That way if the Consultant Certification write failed, there wouldn't be an entry in the Consultant Audit History and vice-versa.

Is it possible to do this in a single Write Records smart service? And if so, how? I see the Setup tab can accept multiple records input but the Record Type field can only accept one.

Thank you so much!
