Feature Request: "Previous / Next Flow Title" in Text Frame

I’m working on a songbook for a band to use at a series of Christmas concerts. They use iPads for the sheetmusic. Some of the songs have sheets transposed for different instruments, some won’t. It’d be really useful to put a text frame at the top corner of my page templates that blows in the name of what music (flow) occupies the following page / layout. In other words, a “Next Flow Title” option or something similar in the Flow Info smart-text menu for text frames. It’d be a great reminder / tool for navigating the PDF songbook on the fly. Thanks.
