I use mostly groups (with IK-handles inside it) rather than curve controls.
When I group some of the IK handles (Ctrl+G) the local rotation axes of this group is not oriented to the local rotation axes of the joint where the pivot is but to the global axes.

Solutions:
1) Orient local axes of the group manually not the answer because you can do it exactly.
2) The way you orient LRA of the curve controls to LRA of the joints
(Parent -> Zero Transformations -> Unparent) doesn't work.
3) Work only with characters joints of those is always oriented to the global axes is absurd because there are a huge amount of characters which don't match this criteria.

Is there any way to solve this problem?
To make it more clear what I mean there is a video of cat rig tutorial but the cat legs are initially straight to global axes (actually to YZ global plane) and in my character - legs (especially foots) are not!
