I'm using 'Tags' column for general tags (e.g. todo, fixing, ocr,...) and '#genre' column for specific tags (e.g. fiction, technology, reference,...). For every new book, I have to copy downloaded tags, delete and paste them to '#genre' column. Is there some way to download tags directly to '#genre' column?
I've considered creating a new column for general tags but then calibre can only add tags automatically to 'Tags' column.

I also noticed that only 'Tags' column has Tag Editor. If it's simple to implement, Tag Editor for custom 'like tags' columns would be nice.
