matching code in vendor subledger

Hello everybody,

My question is: 

is there a field as “matching code” in vendor subledger register (for matched invoices and payments) like it is in general ledgers ?

if there isn’t, is there a way to create a field and personalize the payment matching process in order to feed this field?  And after all post this field on the vendor subledger visualization screen so that we can do filter or sort on it?

thank you!
