When I have two contacts that have an employer/employee relationship in CiviCRM I can use the name of the employer in message templates when I sent messages with the {contact.current_employer} tag.
However I am currently seeing no way to get the name of a contact referenced through a custom relationship (say for example sibling) to use that in a letter. Is there any way to accomplish this in CiviCRM? Maybe something like {relationship_123.display_name}?
