Of course there is.

OtpErlangObject[] tag = new OtpErlangObject[2];
tag[0] = myMbox.self();
tag[1] = new OtpErlangRef(otpNode);

OtpErlangObject[] msg = new OtpErlangObject[3];
msg[0] = new OtpErlangAtom("$gen_call");
msg[1] = new OtpErlangTuple(tag);
msg[2] = o;

myMbox.send("sys_man", "pat@REDACTED", msg);

With reservation for silly mistakes, this corresponds wrapping your o
above inside a {'$gen_call', {self(), make_ref()}, o}
