Contacts such as central recruiters to come up in location searches (postcode or county) from single contact page

Is there a way to link the parent and child organisation sites and postcodes to a contact so that for whichever sites that person may be relevant for spec CV sends will come up for each location added to them

The only workaround is to add multiple contact entities for the same person for each child entity but that creates duplication and also risks multiple central marketing going to them if not unsubscribed, let alone the additional time and administration

My market deals with a lot of multi site clients that recruit for the same roles in different places but may have a small number or single person who covers these sites
