Importing Model Problem (Different MPQ)

Ok, so I have a model I want in my mod (something like Dinosaur.mdx, if you're interested). However, it's from inside a custom MPQ file that overwrites the normal "wc3xlocal.mpq" files (it's the one from the Ominous Horizons group).

If I import it into my map with the pseudo-MPQ in, it works fine (and looks great). However, without it (like most other users), it reads as an error.

Because it's inside the MPQ, it doesn't really have a file path I can just type in (like "Units/Human/Human/Dinosaur.mdx"). So basically, is there a way I can get the WE to treat this model-in-an-MPQ as a normal, importable model, like a recent download? Any help would be appreciated.

Hey, so does anyone have any idea?
