Time and time again it's been stated by OBsIV, he does not want the xim to do anything that a gamepad user can not do. Therefore whilst a ADS macro seems trivial it is still enabling something the game was not meant to have and therefore I wouldn't hold my breath on ANY macro functions being included in xim3 software.
As always, if someone more knowledgable believes I've picked this up wrong then please correct me.
