How to add new service and resolver into existing itinerary from an orchestration?

Hi All,

Though I am working on BizTalk from past 2 years, I am very new to the ESB Guidance.
I have started working on it and have got a basic understanding and flow of the same.

Straight to the point - My pipeline component add an initial itinerary to the message which contains one service instance and the associated resolver for the same which will be used by an orchestration to execute a policy dynamically.
This is how my initial itineray looks like,

<?xml version="1.0" encoding="utf-8" ?>
<Itinerary xmlns:xsi="" xmlns:xsd="" uuid="628c61a6-f697-4ff3-9771-18ae345ad63a" beginTime="2008-05-07T08:37:07.0654864Z" completeTime="" state="Pending" isRequestResponse="false" servicecount="1" xmlns="">
<BizTalkSegment interchangeId="{C3434EAA-30CD-425B-B9F9-A0C30A5DBF7F}" epmRRCorrelationToken="||" receiveInstanceId="{34C0C49A-7422-497A-BF41-F74127742D1E}" messageId="" xmlns="" />
<ServiceInstance uuid="6cf0b3b8-a983-4ba0-9c0c-d9a6aca4fb90" name="PROCESSITEMINVENTORYBROKER" type="Orchestration" state="Active" position="0" isRequestResponse="false" xmlns="" />
<Services xmlns="">
<Service uuid="6cf0b3b8-a983-4ba0-9c0c-d9a6aca4fb90" beginTime="" completeTime="" name="PROCESSITEMINVENTORYBROKER" type="Orchestration" state="Pending" resolve="true" isRequestResponse="false" position="0" serviceInstanceId="" />
<ResolverGroups xmlns="">
<Resolvers serviceId="PROCESSITEMINVENTORYBROKER0"><!CDATA[BRE:\\policy= DetermineMessageType_Itinerary;version=;useMsg=;]></Resolvers>

Now, based on the result of the policy execution in an orchestration I want to add one more service instance to the itinerary and add an associated resolver for the same which could be another policy information for the next orchestration. I couldn't find much help from the ESB guidance document for this.

Can somebody give a code snippet showing how we can add a service instance and a resolver in Orchestration expression box shape?

Thanks in advance for your time and suggestions.
