How to combine 2 non-shippable order lines into one Receivable Transaction

Content (please ensure you mask any confidential information):

We have created a sales order #807250 with 2 non-shippable order lines, each line only has 2 tasks in Orchestration plan: Pause and and Invoice. After we manually released the Pause task for both lines at the same time, we expect the 2 order lines can be combined into one Receivable Transaction. However, the Import Receivable Transactions from AutoInvoice ESS process always created 2 separate receivable transactions. I have attached the 2 rows in the RA_Interface table and the Autoinvoice group rule for the detail. Thank you in advance.
