Aux pivots in CAT

Hi all!

I´m working in a cartoony rigging based in CAT, but I have found some issues I hope can be solved.

For the foot controller (the platform for the whole foot), there is one pivot point which position can be changed through the “Sub-Object” button, but I was wondering if is possible to use more than one pivot at the same time(one for the toe and another one for the heel, like in MotionBuilder), to avoid change the position each time.

Thanks in advance!
