How to change Content-ID on mtom WCF

Question

Is there any way to change mtom href from

xop: Enable href = "cid: http% 3A% 2F% 2Ftempuri.org% 2F1% 2F634599683683634580" xmlns: xop = "http://www.w3.org/2004/08/xop/include"

eg:

xop: Enable href = "cid: [e-mail] " xmlns: xop = "http://www.w3.org/2004/08/xop/include"

Thanks in advance.
