Combining Scores?

I generally use MuseScore for composing/transcribing traditional tunes. When I play these it is generally as a set - 2 or 3 tunes together.

Is there a way to easily combine scores? ie add one or more of my tunes to an existing tune.

I have searched to handbook, but have not discovered anything relevant.

At the moment, the only way I can figure out how to do this is;

1) add empty bar at end of first tune
2) select and copy second tune
3) paste into first tune

The only problem with this is that repeats, time sgnatures, key signatures, part-bars etc do not get copied, so I have to add all that in after I've pasted. To be able to combine scores instead would be a lot more efficient.
