Deleting a frame in score and all parts

Hi!

This topic might have been addressed before, but through endless searching I can not find it.

When I have a project that is just an arrangement of one song, I have the project title at the top of my page in the score and all parts. By default Dorico also puts the flow title underneath the project title, which is completely unnecessary when there’s only this song. How can I remove the frame that contains this information in my score and all parts, without having to go though every part and manually delete it? I figure that there’s a place where I can just remove this information in my music with one motion.

It’s called a Flow Heading, and it can be turned off from Layout Options > Page Setup.
