How to enable Document Sequencing for ORA_OSS invoices

Hi,

We have a requirement to avoid duplication by differentiating the Invoice Numbers generated for Invoices (Regular Invoice) and Subscription Invoices (ORA_OSS_Invoice). Hence, we need to go with Document sequencing for Both the Transaction Types. However, while creating the Doc sequencing, we are unable to find the ORA_OSS Transaction type in the Document Sequence Category Name. Below are the SS for reference.

Thanks,

Vivek
