Bulk generation of invoice distribution lines for unvalidated invoices

Summary:

In Payables, invoice distribution lines only seem to be generated only when

1. the invoice is validated; or
2. the "distributions" button is clicked in the edit invoice state

So for unvalidated invoices, invoice distribution line tables are not populated and invoice distribution line information is not available for reporting in OTBI reports. I noticed this when building a report to assist approvers more quickly review key invoices details before validating in Payables.
Is there a process that can be run that would generate distribution lines for all unvalidated invoices (without actually validating them)? In other words, some kind of bulk process that would do the equivalent of clicking the "distributions" button within an invoice.
