While PowerPoint 2013 lets you attach a connector to any slide object, these connectors can only be attached to wherever you see an anchor point on the slide object. Most of the time, the location of these anchor points may work well for you — however, in certain scenarios, you may need an additional anchor point at a particular location. The good news is that you can add new anchor points for shapes and text boxes using the technique explained on this page. For text placeholders though, you cannot add new anchor points.
