Rapid Rig: Modular V3

Hi! Could you please add the ability to attach different proxy modules (esp. Aux, like for weapons, props) to the RRM_Main proxy? What I would want in effect is these modules' SH joints to be parented directly under Trajectory_Jnt. This will help to avoid weapon shakes and twitches in the game engine caused by a rotation interpolation "inaccuracies" accumulated in the hierarchy and multiplied by the compression. This is what I have to do in most cases anyway, like a post-process, but it would be awesome to have it natively built in RRM. Let me please know if I should clarify the idea/purpose with some images/video examples.
