The ability to associate contacts with other contacts

I would like the ability to associate contacts with other contacts in Trella and put a relationship, so if I meet a doctors referral coordinator, I can add that person into the CRM and then add an association with that provider. I would also like the ability to associate providers with one another who might work in the same building

I’ve worked with other CRMs in the past that had a feature to associate contacts, and also label the relationship
