Applying new features to existing scores

When I open an old score the "Apply new features" dialog box appears. I chose for a couple of test scores to check the box "apply settings don't ask me again" or similar wording. In general I think I like the new settings. But I might have been a little hasty checking the box.

My question, is there somewhere in the preferences where you can turn this option on or off so it doesn't change everything when you open old scores. I'm preparing a collection of hymns and I have worked out all my settings previously and I don't want to disturb these for now.
