How to set recipient dynamically?

Hello,

I have a relatively simple task, that I cannot for the life of me find an answer to.

I have a site for musicians. Each musician has his own profile. There has to be a contact form on each profile. When using this contact form it of course has to send an email to the musician. But how do I set the recipient email dynamically for the form?

I was thinking that there might be a filter that returned the email address before it was send.
Something like:

function set_correct_email()
{
   return $author->email 
}

Add_filter(CF7_set_recipient_email, "set_correct_email")

However I cannot find any such filter. Really hope somebody can help me!
