Default due date , payment method when posting invoice with Special G/L

Hi Gurus,

I have a question is when I am posting an invocie to a vendor (FB60), Due On date, payment method are automatically calculated based on the defaulted baseline date and the payment term in the vendor master. But when I am posting the invocie to the same vendor with Special G/L indicator, Due On date, payment method are not automatically calculated and system are expecting me to enter this date manually. Is there a way we can default this Due On date, payment thod based on payment term like it happens when posting to other invoices without Sp GL indicator ?

Thanks
