Property field type: associate contact / existing object.
In our onboarding, we keep track of referrals. When the referral is: word of mouth / ambassador, I'd like to have a property to associate a contact or company. It would be nice if you could create a property with a field type that makes you able to select an existing contact. Based on this (to be created) property field type you will be able to make new automations / calculations etc.
