I want to transcode FLAC to WAV and upsample the output to 96K. First I changed FLAC output to Disabled under Advanced->File Types, so that all FLAC files will be forced to transcode to WAV. Then I added a custom-convert.conf file. The content of the file is:

flc pcm * *
# FT:{START=--skip=%t}U:{END=--until=%v}D:{RESAMPLE=-r %d}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] -q -t wav - -t wav - rate -b 85 -Lv 96k

The conversion appears to work, but my Transporter is still thinking the output is 44.1K instead of 96K, so the playback is run with the wrong clock. How do I tell TP that the output is 96K?
