As mentioned in the previous update, we are now in development of updates to the CRM that will make adding multiple companies to a single contact possible. Not making timeline promises in this forum, but as soon as the beta is available, I’ll notify this thread.
To those wondering about using Custom Objects for associations - I would recommend against it. Custom Objects are great for the “nouns” of your business (think inventory, shipments, appointments, real estate) but not as good for describing the relationships between things.
We’re focused on getting this updated functionality to you soon. Stay tuned for updates.
