Calibre already has the list_re function to be able to apply a regex to every element of a list, but is there any way of applying other functions to list elements?

(Specifically I want to be able to apply shorten to every element of a list; I want to be able to achieve something like the sample program listing in the Calibre template language reference but my series column is often a `.' separated list of nested series.)
