Say I have books 1 and 3 of a trilogy, and add them to calibre. A year later I finally locate book 2 and add it too.

Now the series is split in two different places in my library (which I like keeping sorted with newest books at the top).

Is there a way I can change the date-added info in a sufficiently fine-grained manner that calibre's sorting would insert book 2 in-between books 1 and 3? Say, 1 second after the time that I added book 1, but before book 3.

(I'm actually trying to insert a dozen scattered issues into a 100-issue magazine run, so it's a little bit more complex than the above...)
