More than 99 books in a series

Hi. Is there a way to register more than 99 books in a series?

I have a series with 175 books (written by the same writer, with the same heroes), and I would like to write, in the 'Number zone': 1,175, 2,175, etc. but Calibre seems not to allow that, and writes 1,17, 2,17, etc.

Thanks for any help.
