This connects to my answer on the other thread where I recommend that you use Contactsā¦
Remember that itās normal to use Contacts for many different kinds of things. You donāt always need a separate module for different entities, it might be better to simply segment the records with some kind of type field. So you could have some Contacts marked as customers, others as Agents, etc.
Custom list views and filters will then show you only what you need to see, where you need to see it.
