How to loop multiple records in OIC Target side of Mapper

Summary:

I would like to know if it is possible to iterate through a list of hard-coded values (Transaction ID) for the "Transaction Interface Id" field below. I do not want to pass in a data source from the Left side, and would like to know if I can iterate through multiple target ID values I would provide.

Content (required):

I attempted doing this by inserting a for-each loop below on the Staged Record Transaction, and then adding two distinct values in the Transaction Interface Id, however as you can see this causes the below error when I try to validate it.
