Large Orchestra version and Chamber Orchestra version in same file

Ok, up until this point I have successfully kept two versions of the score in the same file – a chamber orchestra version and a large orchestra version which simply adds trombones, a single percussion player and switches from 2 to 4 horn players. I duplicated the layout of the chamber orchestra version to the large orchestra version but the only issue is that the front matter still seems to be linked to the chamber orchestra version. When I try to change the text to large orchestra, it changes on both of the scores which is problematic. Is there a simple way to fix this? Do I just rebuild the front matter from scratch for the Large orchestra version? I cannot attach the file because even in silence mode its 5.4MB

Thanks, it appears starting from scratch is the way to go.
