XF 1.5 Censoring as autocorrect almost works

We use XenForo 1.5.9 (currently) for the FreeNAS forums. Users have difficulty capitalizing FreeNAS, so I tried setting the correct version as a replacement through Censoring. This works great... except when the string is a literal, case-sensitive one like the name of a system. That turned out to be more common than expected.

Is there something similar to the Censoring option that is able to leave text inside code or other tags unchanged?
