Sample current space transforms for constraints "limit loc" and "limit rot"

Just as the object/bone constraint "limit distance" has a "reset distance" button that samples the current distance to target object/bone, a similar feature for the X,Y,Z channels on the "limit location" and "limit rotation" constraints is useful; i.e., for a button "sample current space transforms" the sampled coordinates/transforms would depend on the owner's configured "owner space" dropdown.

It would allow to key and freeze a transform in space if a bone or object for instance is already parented/constrained to other targets without necessarily having to release said constraints and parent relations and remove the need to use "copy transform" constraints with helper empties/bones to achieve the same end.
