I assigned as a test an External ID to my contacts, from 1 to 28, but I'm not sure if individual contacts who work for one of the affiliated companies should be given the same External ID as the company or if I should assign them a different External ID (as long as that company is also in this contact template). If the contact does not belong to any company, I understand that they should be assigned their own External ID individually.
