Instead of a .cr2, make it a parented prop. Load the object and place it in the figures hand. Then go to the menu and select. Object:Change Parent. On the list that comes up, select which hand you've used with the prop. Now save the prop to the props library. It will ask if you want to save it as a Smart Prop. Select yes. Now everytime you load the prop, it'll go straight to the hand. Most of the time, there is no reason to make a .cr2 file out of something like a staff. A staff is a rigid structure. Only bendable or posable things need to be .cr2 files (like clothing).
