Sheet Metal Hem - Mitered Corners

I'm fairly new to using the sheet metal functions in SolidWorks, so bear with me please.  I have a simple part that will be a shelf.  I want to hem the front and sides to prevent sharp edges.  My question then, is there a way to have a mitered corner where the adjacent sides come together in the front?  See image below.

Thanks for your help,

Steve
