Dizzi, FII addresses this issue, and permits injections to any figure in a scene, even identical ones. You direct Poser to inject the correct figure simply by selecting the target figure as the current figure (ie. you click on it ;-) If by chance you have Migal's Stephanie Max - which is built FII-compliant - you can test this concept out by loading 2 copies of SMax and inject different morphs into each.
