Aura Any ways to display page numbers directly on the sleep screensaver?

Hello,

I recently began to use the full screen mode on my Kobo Aura (no footers and headers), which is really great. But by doing so I have only access to the percentage read both on the screensaver info box and when I touch the middle of my screen to trigger the info/time/settings menu... Which bothers me a little since I don't know how "big" the book I'm reading is...
I wanted to know if there was a way to display "pg 25 ouf of 500" on the screensaver info box? (or at least when it alternates with the time after touching the middle of my screen)

Thanks :D
