Flexible Pagination

I'm nearing the mid-point of a very large project that spans multiple files, and I'm wondering about my page numbering options for the final books. The conductor score itself runs to several hundred pages, and several of the individual instrument parts are quite long as well.

To that end, I have some questions:
Is it possible to have the page numbering for each part reflect the total of each movement?

For example, if a trumpet part is six pages long, could the page numbering show 1/6, 2/6, etc. (or the conductor, 1/42, 2/42...) This is fairly common in pit orchestras, and is very handy for rehearsal purposes.
Could Musescore do this automatically? I can't imagine the time it would take to tabulate each part manually.

Secondly, is it possible to run page numbering sequentially across files throughout the entire score? For example, if the second number in the show begins on page seven, can Musescore reflect that reality?
If the combined trumpet files add up to 80 pages, or the conductor 600, can this somehow be shown on the page?

This is also very common in published scores.

(I doubt that it helps, but my files are all numbered sequentially, (1-01, 1-02, etc.))

As for how this might all look, I've generally seen it with the "master" number centered at the bottom of the page, and the "movement" number at the top of the page or justified right at the bottom.

I've been in pits where books are sometimes missing pages, or pages are out of sequence, and it's a lot easier to fix if pages are fully numbered.

Thanks,
