Purchase Invoice Numbers Not Copying to Good Receipt

[VACUUMDOG]

Using ver 21.9.26.
Purchase Invoices do not have a field for ‘Invoice No’ just ‘Reference’ which, when entered, appear as ‘Invoice number’ on the viewed Purchase invoice.
When copying to New Goods Receipt the number does not copy to the ‘Invoice number’ field.
Is this by design or does it need fixing?

Fields Order number and Invoice number on Goods Receipt will eventually be gone (converted to custom fields if used).

And the mechanism of linking purchase invoice to goods receipt will be the same as it’s already implemented on sales invoices / delivery notes.
