Name of banner "collection" above the image

All right, I have searched the forum and found a couple of people looking for the same thing as me - and no answers.

So I am setting my hopes on explaining it better. First a few definitions:Opencart has "banners" built in. Every banner consists of one or more images.

I run a site on Opencart 1.5.6.
I have several "banners" on my page. They are collections of about 5-10 images each. To distinguish between them, I would like to display the name given to the banner-collection in System->Design->Banners right before where the banner is displayed.
Not the name given to each individual image. That is already taken care of, but the actual name of the collection.

Just a few hints on what files are involved would be nice, that way I am sure I can mod the way I want to.
