Many thanks for great solutions @Isherwood and @DarkLaguna

!
I have a problem with metadata respectively Kindle sort of translated books:
Author: Том ДеМарко (Tom DeMarco) & Тимоти Листер (Timothy Lister)
Author Sort: ДеМарко, Том & Листер, Тимоти
If I use Author --> author, then I can search by author (latin characters), but Kindle sort is by FN;
If I use Author Sort --> author, then Kindle sort is by LN, but I can't search by author (latin characters).
I would like to have both

...
Have you any idea

?...
