Im building a Apartment rental site.
And on the single apartment page I have a “Send a private message” button where people can send a private message to the person who owns the apartment and ask a questions.

So therefor I need to automaticly add the Apartment name in the Subject of the message.

Is it possible to make the subject within the URL something link “https://domain.com/members/user1/messages/compose/?r=user2?subject=xxxxxxxx” So the Subject is automaticly filled when people clicks the “Send a private message”
