input offline sales into madgix from crm or manuallu

Need to be able to input manually or have a connection to a CRO to use ROAS on madgicx. I talked to meta and they dont use conversion data on the API to improve the ad delivery. Basically,l we are stuck with connecting the CRM to madgix or at least giving the user the opportunity to give the right sale attribution to each lead. Nobody is doing this and doesn't seem difficult to implement for healthcare related businesses.
