Clearing Account Reconciliation design in ARCS

Summary:

Hello,

I am designing a cash clearing reconciliation in ARCS for two clearing GL accounts. My objective is to:

1. Load a transaction population via CSV file.
2. Auto-match transactions based on common attributes.
3. Leave outstanding timing differences unmatched.
4. Reconcile the remaining unmatched population to the GL balance.
5. Route the reconciliation through normal preparer/reviewer approval workflow.

Initially, I created a single-source Match Type because all transactions are loaded from a single Power BI report. Transaction matching is working as expected using this approach.

However, when creating a Balance Comparison with Transaction Matching format, the single-source Match Type does not appear as an available Match Type, while a two-source Match Type does.
