Can you display more than one album cover

When using Advanced/Formatting/Artwork to enter a different name for an album cover, what is the result supposed to be. Is it supposed to display more than one cover for an album. For example, I use Folder.jpg to identify my album covers in the LMS, but I may have additional covers in the music folder. So if I have a jpg in there called backcover.jpg and I enter %ALBUM-BACKCOVER.jpg in the Artwork field under Formatting, what will happen??

I hope that was clearer than mud.

Thanks,

Howard

BTW, using LMS 7.9.1
