        This isn't quite what you asked for, but it may be good enough.  You can draw a set of ROIs (rectangles, ellipses, polygons, lines or freehand marks) over a slice using Analyze/Tools/ROI Manager.  You have to draw on each stack one at a time, but it's just a keystroke and a mouse click.  If you want, you can measure any or all ROIs in any or all stacks simultaneously.
