Channel Checkboxes for NLA Modifiers (effect only specific channels)

NLA modifiers currently effect all channels of an action clip "globally".

For example, if an action clip has keyframes for say both location and rotation within it and a user applies a NLA noise modifier to that clip. The noise modifier will effect both the location and rotation channels and there are no options to filter the modifier to affect specific channels independently.

Therefore I propose that NLA modifiers be given the similar functionality to modelling modifiers and constraints and allow users to filter the effect of the modifier to individual channels. Such as Location, Rotation, Scale, X, Y, Z etc.

Thanks
