Calibre will do what you want during a conversion. It can add a "jacket" near the front of the book. I think it is put as the first page after the cover. For an ePub, the "Modify ePub" has an option to add the jacket without doing a conversion.
And I remove all jackets using Modify ePub.. It's just a page I don't need and don't want. It takes me less time to dump the jacket then it does for you to add it. If I was going to give it out on the net, I'd first remove the jacket and then distribute.
