How to use transform mask when importing animation

Hi everyone,

I've found that some animations that I need to play at the same time conflict with each other, so I thought I'd use the Mask > Transform option in the import menu for the animated model. The thing is that when I disable transforms it seems to have no effect. I have "Definition" set to "create from this model". If I try to create the mask from another mask Unity says that I have no other avatars in my project. How do I use the transform mask to limit which animations control which transforms?

Thanks in advance.
