What I have always done is type the split times into a text file, then "shntool split -f splits.txt -o flac -n xxx2010-10-20d1t blah". It's seems tedious, but I also type in the song titles at the same time. From there I have a bunch of homebrew scripts that would take it from there to generate my .txt file and my flac metatags, etc. In the end it reduces my overall workflow.
