Simple. Ingest with FCP Log and Transfer (which will leave your frame rate alone), then open the resulting clips in Cinema Tools and Batch Conform to the desired frame rate.
To make the process easier, I add a suffix to the file names of clips that are overcranked: Something like _59_94fps. That makes them stick out in a Mac OS file list.
That is an older method. For newer options, Digital Rebellion's Pro Media Tools also does this job.
