Mapping multiple SIP Diversion headers in an INVITE

Is there a way to handle multiple diversion headers in a SIP Invite ?  We need to be able to access the values of both Diversion headers.  Using SIP Server (INVITE) mapping to T-Lib messages, we get two Diversion KVPs attached to the call, but we can't access the value of the 2nd KVP using the assign function in IRD, or any other function that we have tried.
