[SR-Users] Using dispatcher module : Modifying message before dispatching with send_udp()

Hello, I am using the dispatcher module, Kamailio version 5.3.3. The point is, I am using send_udp() to forward the message, because I don't want Kamailio to add headers Via nor Record-Route. I am just dispatching the Invite message, and the rest of communication to be made just between the endpoints, not through Kamailio. However,  I need to add before a custom header, using append_hf().  It seems, send_udp() really changes nothing at all in the message, not even something added by the script with append_hf(). It works if I use forward(), but not if I use send_udp(). Is there a way to accomplish this?
