An option for Base CRM to add this functionality, is to allow the end-user to create custom Company Account fields based on other fields in Base CRM. For example, it would be great to create a custom field called Parent (for Parent/ Child type relationships) or Associate or whatever you would like to call it, then that field would linked to Company field. Similar to, when adding a contact, and you want to add a company to that contact, the Company field does a look-up of the Companies in Base CRM.
Using this feature, we can build as many relationships as we wish.
