Setting default distribution segments for non-PO invoices

Summary: We have a requirement to set up default distribution segments (not the entire combination) to speed up the manual invoice entry process. We have tried using TAD (Configuring Subledger Accounting for TAD) to achieve that, but an error is coming up as we have not configured rules for all the segments, as follows.

The first and third segment should derivate from the Legal Entity and the rest would be a constant value of zeros, excluding the natural account which must be entered by users while creating an invoice. On EBS we can default some segments only (attaching another screenshot showing that), we would like to replicate that to Cloud.
