Maintaining format of copied project

[gregm]

I've created a global project schedule from several separate MS Project
schedules by inserting a link in the global schedule to the individual
schedules. I wanted the global schedule to maintain the special formatting
used in the other schedules, such as the coloring of the gant bars, but the
formatting used is the default format of the global schedule. How can I
maintain the format of the separate project schedules when linking to them?
I've even tried copying the entire separate project into the global project,
but the formatting is still lost as it get's over-ridden by the format of the
project that it's being copied into.
