I simplified what you poasted earlier for easier testing for me beacuse I'm not great with regex but this is what I have now:
Code:
[test1.com]
extracharacters:Harry P.,N. Tonks,Daphne G.,Hermione G.
custom_columns_settings:
## Character list
characterlist=>#charecters
# 'add_to_' concats on to existing param, thus the leading comma
add_to_extra_valid_entries:,oneshot,tagscategory,characterlist
include_in_characterlist:characters
replace_metadata:
## Fix and standardize your character names first
characterlist=>Harry P\.=>Harry Potter.Harry Potter
characterlist=>N\. Tonks=>Harry Potter.Nymphadora Tonks
I'm very interested in your method for bulk fandom prefixing so I'll watch that, but this is working and using a text editor I can quickly update my old ini so thank you a bunch.
