Several pieces in one file

I have this songbook that contains about 30 very short songs, some of them only one or two staffs.

I'd like to avoid any post-processing such as putting PDFs generated by MuseScore in some graphics editor.

What is the "right" approach for this? Currently I am doing this:
- adding one extra measure at the end of a piece
- inserting section break before that last measure
- adding text frame above the newly created staff
- writing the new song title in that text frame
- formatting the text frame as "Title"
- specifying the clef, time signature and key signature, as they are automatically inherited from the previous piece

Well, this works, but I am not sure that's the best way, feels quite hacky. Sometimes, if I forgot to use the section break, specifying the signatures for some piece spoils the signature for the following piece. If there is the "right" way to do it, I'd like to learn about it.
