[VoiceOps] RPID vs. PAI

I am working with a provider that wants to see PAI and not RPID, however we receive calls from a different provider that sends us RPID. Can I simply copy the RPID header into PAI so that all the necessary screen= and privacy= parameters are preserved when forwarding the call from the second provider to the first? Is there a better way of going about this? Thanks for your help. David
