Agent signature on Side Conversation child ticket

The original method for a Side Conversation includes the Agent Signature.  However, the child ticket option for a Side Conversation (SC) does not include the Agent Signature.  While the agent creating the child ticket does become the requester, it would be helpful to also have the option to include the agent signature, so that it looks more like what a normal email would like when converted into a ticket.

Our workaround is a macro that creates the SC.
