Citation key generator and Linked files

A tabular construct similar to "Key patterns" is sometimes required for "Linked files (Filename format pattern)".

Some examples:

1. Book file names are not always long enough and can be fully described in the "title" including also the date and first author:

2024_Medium-length_book_title_ (author's_last_name)

2. When considering a “PhD thesis” since titles can be quite long, you can limit yourself to the first few words of the “title” and add a note that this is a [PhD thesis], like here:

2024_A_few_words_from_the_title_...[PhD_thesis](author's_last_name)

For the examples discussed above, it is necessary to change the “Filename format pattern” pattern each time, although there is no such problem for “Key patterns” due to the tabular design.
