Adding episodes on the doom menu for vanilla

Is there a way using dehacked or another patch file? and then, is it possible to load an E5M1, E5M2 etc on vanilla? Thanks :)

For vanilla, the only thing you can do is change the names of the 4 episodes in Doom 1, by changing the graphics M_EPI1 through M_EPI4. Can't add new episodes, and can't have any kind of episode selection in Doom 2.

I thought the same, just hardcoded settings, but you never know..
