Feature: choose pages

It would be great if you could choose which set of pages of a pdf to print as a booklet. I often want to print out sections of a book and it would be great if this could be done inside the app instead of having to first create a cut down pdf before uploading.

The UI isn't as friendly, but the Villainous Imposer Program (another free online imposition tool) can do that currently -- https://sithel.github.io/vip/
