When you import a song, that's the version that appears in your sets and books. There's just one version of the song, and it is saved in your All Songs list. Consider this the master version of the song.
If you want to change details like key, MIDI changes, sticky notes or drawings, etc. from this master version when you add that song to a specific book or set, you will need to use Separate Styles. This is an option that you can turn on at the book or set level, or configure it to be on by default.
Books
When creating a new book, locate the
Separate Styles option in the
Book Editor. This is set to Default which means it will use the default option you've set. You can change from the default setting here by choosing On or Off. You can also change this setting after the book is created by tapping on the Edit button in the
Books Menu to enter
Editing Mode and then tapping on the name of the book to display the
Actions Menu. You can then choose
Edit Book.
Sets
When creating a new set, locate the
Separate Styles option in the
Set Editor. This is set to Default which means it will use the default option you've set. You can change from the default setting here by choosing On or Off. You can also change this setting after the set is created by tapping on the Edit button in the
Active Set Menu to enter
Editing Mode and then tapping on the name of the set to display the

You can change the default configuration by tapping on the gear icon in the
Menubar to open the
Utilities Menu and then choose

Menu Settings on the left and then
Songs on the right. Locate the
