Visio 2010: replace a shape

I asked this question directly to the Program Manager of Visio 2010 at Microsoft during an internal MS event on campus and the answer was: "This is not possible". I have been missing this feature since Visio 2003 and hope that it will be finally added in the next version of Office.

An update: this feature was added to Visio 2013
