Changing the Scale of Multiple Units at Once

[Dodighead147]

Hi. I want to make a sort of massive SC2 map. However, I don't want to have to go through every single unit and each of their submodels and change their sizes individually. Is there any way to change the scales of all units (maybe in the whole game) at once, or at least all of the submodels (i.e. Marine: Marine death blast, Blood Target Impact, etc.)?
Thanks for your help.
