Hello i have 11 source input feeds and i want to ask if is possible when i do a mapping the fields to have information like prefix before the fields to know which source input feed is by the id for example.

it will be useful to make it work correct because the information is there like the id on source feeds so i think is possible to get them from there that information like 1.title with 1. is the id 1 input feed or something

Please tell me if that is possible or it can be done with extra cost to make that feature available
