Importing MCreator-made mods in Mcreator

Is it possible?

I mean, as the first folder you found under the "net" folder of the mod file of say Create: Stuff & Additions (that is an awesome mod that you should definitely try) is named "mcreator".

I therefor deducted that it was made with mcreator, and hoped that mcreator had some opening capabilities, cause i really wanted to custom this particular mod, for my free server.

If you have any idea, or paths for me to follow, feel free to comment!
