Cover art for individual podbook chapters?

[xancredible]

So, I've got a project coming up where I'm (hopefully) going to include artwork for every single chapter (possibly even half-chapters....) and that's pretty easy to do for an mp3 podfic, because you just create several files (as I would anyway, considering that this is going to be a 10h podfic) and imbed the cover art per file.

However, is it possible to add covers for individual chapters for a single podbook file? Does anyone have any experience with this?

Thanks for your help, guys!
