This also happens on my T1. This is what I did (with the help of chaley the plugboard developer) to reduce the aggravation:
- Set up an extra plugboard using EPUB/PRST1 which duplicates your device_db/PRST1 plugboard mapping for {authors}
- Resent all my epubs to the T1
This extra plugboard will insert your customised author name into each epub during the send-to-device. It won't stop the T1 from throwing away your plugboard info but when it tries to re-extract author data from each epub it will be extracting the same customised value as it just threw away.
These are my two:
Code:
device_db:PRST1 = ([{author_sort}{series:| - | }{series_index:0>2s}] -> authors)
epub:PRST1 = ([{author_sort}{series:| - | }{series_index:0>2s}] -> authors)
Hope this helps
