Greetings everyone, 

I'm trying to create a werewolf short, but I've hit a wall and don't know what the solution is to be able to continue. 
The Morph Creator has a limitation listed below:

75% of original size (was 671x19) - Click to enlarge

This creates a big problem when trying to do things like scale a model. Without some kind of "blend shapes" or "shape keys", I can't create any sort of transformation short, which I need for my work project.

Does anyone know a possible workaround or workflow for this? 
Any help would be greatly appreciated!
