Partial Payment via lockbox should not be applied and should be as unapplied on receipt

Hi Team,

Lets say AR invoice balance is 1000 USD and customer pays us only 800 USD and when we receive funds from the lockbox it will apply 800 and against AR invoice 1000 and 200 will still show as balance due.

So this case will be short pay, is there a way where instead of applying 800 to the invoice it should be as an unapplied on the receipt.

Thank you,
