Mortgage and Insurance

I have two Bank of America revolving accounts under my belt. One is a credit card and the other is a line of credit. Both accounts have been closed for more than a year, and I made special agreements to pay them. Both accounts get reported on the credit bureaus as revolving. Is there any chance to ask BoA to report those as installments since they are being paid in fixed payments each month and the credit lines have been closed? If so, will I see improvements in my credit score and report? Thanks.
