Converting Field Codes on export

[shrthrnPLS]

Ran into an interesting issue on a project with codes. We currently are running the latest version of Carlson Survey on a large topographic project. We utilize field to finish to complete all our linework, symbols, attributing, and labeling. Currently our F2F is pretty extensive and detailed. The current client has not come to us wanting us to utilize their new coding requirements for field work. I have been looking for but have not found where I can export the points we have and change the coding to their coding. Let me give an example. We have individual codes for Power pole, Deadman, Drop, etcs. (These are a numeric based code). Their code is Power symbols (Also numeric based). I would like to find something that could translate these codes into that simple code with out going to manual change every code on an extremely large project. For those that are familiar, something like mapping layers to levels in MicroStation. Any help would be greatly appreciated.
