Looking for Suggestions

Hi - I'm looking for some assistance from the community - you all have helped me many times in the past.

I have a large work for Concert Band that consists of 3 movements. Each movement exists as a separate file; right now I only have the full conductor's score to each; no parts. I have submitted it to a local organization, and there is interest in performing it, but here's the rub - the conductor wants the parts to all print continuously. How can I combine the individual parts for a given instrument - say second Trombone, into a single file, that would exist something like this....

Title
1st Movement name
Ist Movement music for 2nd Trombone
2nd Movement name
2nd Movement music for 2nd Trombone
3rd Movement name
3rd Movement music for 2nd Trombone

Let's assume what is perhaps obvious - that the movement lengths are different, and do not necessarily occupy a complete page or number of pages.

I have done some searching through the Forum and Handbook, but part of the issue is what this type of activity is called. It does not seem to qualify as a "merge", as the parts are to be added. (entries on merging seem to center on adding various parts together - such as Soprano and Alto into a single stave). Combing is another possibility, bu this seems to be another term for Merge Append seems more appropriate, but I don't want the parts to be continuous measures. As stated in the outline above, i'd like a movement to end, a new title (in a frame) to appear, and then the next movement would start. It would be nice to have the measure numbers start over at this point, as my rehearsal marks are measure numbers.

It also seems to me that I might create the parts in PDF format, and then use a third party product to combine them, but I would think this to be cumbersome, since the PDF product wouldn't really understand the content of the individual files, but would see them as just a collection of pixels.

So, I am asking for ways to accomplish this. At this point I am open to suggestions, and am sure that someone (or more) of you have ways that can use to solve this issue.

Thanks in advance for your time and support.
