I was just thinking about asking for this feature. Simplify3D already does the generation of gcode to send to the printer so it has everything already calculated from the model. If I am printing 12 of something and notice the 4 and 8 objects are not printing properly, I should be able to hit a "Pause and Adjust" button that takes me back to the "main view screen" (Simplify3D could save the last print position sent to printer). From there I could delete or mark objects 4 and 8 for not printing (and clean the print bed of debris from the failed prints) and then click resume. I'm a developer and it doesn't sound impossible
