I have a contact who works in two different companies. I want to associate to this two companies, but i can´t do it. If i associate to one companie the contact de-associate to the other.
I guess, that the unique solution is to duplicate and create a contact-2 to assign to the company B.
It is possible to c[reate parent/child relationships between two companies](http://create parent/child relationships between two companies) and then associate the parent company with the contact in question.
Seems to separate the communication pretty effectively, I cannot figure out the logic without further digging though. Email subject is a guess, sending relevant emails per deal through Hubspot from the email tab of the Deal would be the way to safely do it.
This is now possible! The feature is in early access and you can opt-in for early access to the new associations, more details in this knowledgebase article:
