How automaticly create actors when meshes and textures are already imported?


I have a lot of muscles. For each of them was created folder which contains meshes (parts of muscle) and textures. For example, folder “deltoid” contains 3 muscles which belongs to deltoid and parts of each of them:

For initializing 200 muscles it seems wrong idea to do it manually. At least, because making changes will be much harder.

So, is it possible write some bat / python / another script which done it automaticly?
Or some tips with C++? As I see actors created after BeginPlay() or in PostInitializeComponents() is temporal and cant be saved. And new actors cant be added in constructor of own class (inherited from AActor) because GetWorld() return NULL consequently spawning isn`t possible.
