How to horizontally center systems over multiple pages?

[josh]

Hello,

I have a score that has system breaks (defined by \break) at specific random intervals. Some systems have two bars, some have eight, some have twelve, etc.

I have ragged-right set to true and I am looking to horizontally center every system on its own page, regardless of length. I have tried the methods here and here but I have still come up short.

I have attached the drill score to this email for reference. All of the part definitions refer to an \include file. If there's any other information that would be useful I'll be glad to provide it.
