Force Boox Library to Update Cover?

Hi all!

Quick, little question. I've started moving toward using PDF notebooks for various tasks rather than using the built in notes app. Many of these notebooks have cover pages with room to note what's in the book. As I tend to use these things for either a quarter or a year, this isn't something that has to happen regularly, but it would be nice if the cover image in the library would update to reflect my scribbling on the cover.

I can force this to happen if I copy the file to another folder and then back to where I want it, but I wondered if there was a less cumbersome way to force the cover image to update. Detecting and Embedding the data doesn't trigger it.

If it makes a difference, I'm on a Note Air 3C running the latest firmware.

Thanks!
