Oh, I thought you were already using Trizbort’s automapping. It has an automapping feature, you turn it on and select the text file of the transcript you’re using. It will extrapolate, very intelligently (but not 100% without any faults whatsoever), a map based on the transcript.
There are a few caveats associated with this feature and its limitations, so you should read the help file to find out what they are.
