Subject: Keying with multiple masks and zero overlapping

Hi friends, 

Overlapping masks Ae question: 

So after keying some footage, I had to do multiple keys on a figure and I masked different areas with different key procedures. Head, body, shoes etc. each in different layer (a copy of the original footage). 

obviously some overlapping occurs between masks and if I am with areas of semi transparent areas on top of each other, I would wish to avoid that. If these were 2 masks then the solution would be simply linking them and using subtract on the other so there is no overlap but what if these are 3 or 4 masks overlapping? How do I make sure there is no alpha overlap between them and preferably keep Them linked? I mean how do I overcome this multiple alpha scenario other than carefully moving and blending them Manually (and if there’s animation then each change also need to readjust) 

In mocha you can link splines to each so guess I would do that next time but Any thoughts about keying efficient use of multiple masks with 0 overlapping? 

Thanks
