I would like to know how I can link a person to two organizations
Hi @Manuel Fernandez de Canete , this is not yet possible, in the mean time you can best create an "organization type" of custom field under the contact persons: https://support.pipedrive.com/hc/en-us/articles/207228075-Custom-Fields. You can call this for example "second org" then you can save a second org on the contact person details.
Our team is already looking into this and investigating how it can be further improved. I will be sure to register your feedback 📝
