AMFP assets in TDD Level editor

[Villain]

My sincere apologies if this has already been answered and if so I will delete this instantly.

So I used to do a bit of level editing a while back (which I'm pretty good at, if I do say so myself)

and I wanted to map out a new custom story (I would make dozens of detailed maps but never create a custom story as I don't know the coding very well)

and I wondered if there was a new level editor or if it was as simple as copying and pasting the machine for pigs assets into The dark descents folders?

anyway, thanks!
