repetetive tune in series

[Terka]

in series, there usually exist some repetetive tune part (after the early beggining)
its like this:
s01e01 beginning
s01e01 TUNE
s01e01 rest

s01e02 beginning
s01e02 TUNE
s01e02 rest

bold parts are the same in every epizode.
so they waste space.
is it possible to have in CONTAINER a link on the TUNE which will be in separate file, instead of the data?
Hopefully its clear what i mean.

Yes, it's possible using the Matroska container, but it takes some time to understand it. Read this article (http://mod16.org/hurfdurf/?p=8).
