First of all: THANK YOU for your work and all support you are offering.
I tried to get answer to my problem with browsing and try/fail, however I can not quite get the solution.
I sort my stories in Calibre so that Series field (built in, not custom) is based on Rating from SOL. So if rating is No Sex, I have series 'SOL - No Sex'. Sure, I was able to change Rating text based on value (rating=>No Sex=>SOL - No Sex), but I am not able to populate Series field with this.
I thought I could replace metakey with another (series=>rating or series=>(.*)=>rating), but it is not working.
I also tried custom_columns_settings (works nicely for my custom columns) like score=>#myrating, but I can not get it to work for ex. rating=>series.
What am I missing?
