Upsert using data from table

Hi, I've checked the article Could you please recommend to me the article where is described how to reference both updated (several) records and the new record using Action Type "Bulk upsert via a primary key" in the "Array of records to update".

Please mind that user can behave in the following scenarios:
a) only add one new record
b) update several records
c) update several records and insert one new

The sample application is here:
