Sort of. When you first save the song, it will analyze the chords and recommend a key-signature change if required. This is shown in a green box at the lower right-hand corner of your monitor.

However, I don't think it actually works. Well, it didn't work for me anyway when I just tested it. I created a small test song that should have ideally been in A minor. I clicked on the box as recommended and the song key-signature stayed in C Major.
