Code:
## (Plugin Only) - You can also populate calibre custom columns with
## the site specific metadata using custom_columns_settings (but only
## if 'Allow custom_columns_settings from personal.ini' is checked in
## the plugin GUI config.) There are three parts, the entry name,
## then the label of the calibre custom column, then (optionally) a
## 'mode'. 'r' to Replace any existing values, 'a' to Add to existing
## value (use with tag-like columns), and 'n' for setting on New books
## only. (Default is 'r'.)
I'm guessing the answer is 'no,' but is there any trick for making a custom column setting
only replace pre-existing values, instead of applying to new books?
I have #onkobo as a bool. 'Yes' means (current) version is on device, 'No' means that it needs to be synced, undefined means it's not on there at all. I just want the updates to set it to No, not have it set on every new fic.
EDIT: If not, I added a search & replace to my fanfic-cleanup action chain (run only on new fics) to null out the column.
