BeyondTrust PRA and RDM

Has anyone used RDM as a front-end for BeyondTrust PRA (privileged remote access)? I know there is an integration between RDM and BeyondTrust PasswordSafe, but what about with BeyondTrust PRA?

It will either be through the integration or using PRA protocol tunneling. My bet is it's probably through protocol tunneling as the API commands for PasswordSafe and PRA vault are different, so the integration probably doesn't work. thanks!
