In PowerPoint 2013, does anyone know a way to enable snap-to-grid when drawing freeform objects?

I have been using MS Office 2003 forever and recently upgraded to 2013. Much to my dismay, I discovered that the snap-to-grid feature does not work when drawing freeform objects. Now there is no way to rapidly create odd shapes with precisely positioned points. A huge time killer for me. Its stuff like this that made me stick with 2003 for so long.
