Can we populate Asset Book from PO in Invoice Creation page?

Summary:

We have a business requirement to transfer PO-matched invoices to the Fixed Assets Dashboard using the Create Mass Additions process, but without enabling the "Track as Asset" option.

During our proof of concept, we observed the following:

If the asset clearing account is manually entered in the PO charge account, the Asset Book is automatically populated at the invoice line level in Payables.
Similarly, if a Category Name is assigned to the PO and that category is linked to the correct asset clearing account, the Asset Book also gets populated automatically.
However, we’ve encountered an inconsistency: sometimes the Asset Book is populated, and sometimes it is not, even though the setup appears to be correct.
