Another JCM question

Hiya,
SO thanks too Josh Darling's youTube video I've successfully learned how to make JCM's and it's allot easier than you think. BUT I'm finding that if I use two bends at once a new crop of poke throughs happens so was wondering if there is a way to create a JCM that can included two or more bends?
Say you have a "knee up" bend that involves the thigh up to about -105% and then the shin bent to about 140% creating a knee up bend... I really need to know if there is a way to make a JCM that would involve this sort of action and would kick in when both are utilized..... If not then there must be a work around or another way.
Thanks every so...
Rich

This question came up a few days ago in the Nuts 'N Bolts forum:

You will need to create an MCM which works on both joints (1st Stage Sub-Components), and then link that MCM into the respective JCMs for those joints (2nd Stage Sub-Components). The tricky part is working out the MCM Scalars for each of the joints. I included some formulae for these in my answer in the other forum. If you want the morph to only work with, say, Michael 6, you will also have to link to the FBM for Michael 6, but the scalar in this case will just be 1, as with an ordinary MCM.
