Save and retain code in POP record invoice function restored

Within POP, record purchase invoices, there is the option at the bottom of the screen to save and retain the account code - but we are unable to access this - I believe this is because the same screen is used for entering invoices through Purchase ledger, where the option does work.

Is it possible that the 'Save and Retain' option within POP could save the invoice details and then revert back to the POP order selection screen for the same Supplier? This has the potential to save hours of time on data entry- our Company enters dozens of invoices through Purchase Ledger each month, but we enter in excess of 1,500 invoices through POP record invoice details. Our Software provider has mentioned that they are frequently asked for the same function by other Companies, so this may be a popular fix if at all possible. Fingers crossed.
