Facebook Leads Ads feeder - Platform identifier mapping

Facebook Lead Ads is an older cloud integration app and potentially was not updated since Meta acquired Instagram.
Since the new ad form creation can potentially create ads in both platforms and the form submitters are coming thropugh the same feeder, it can be an essential information whether they are from facebook or instagram.
This is presented in a system field called Platform(values are 'fb' or 'in' respectively), and it could perfectly serve this purpose, but these system fields(along with a couple other which are actually available when downloading the submitter details from Meta in excel) are just hidden from the Feeder, they do not come up for mapping on the canvas in eloqua.
