ControlTemplate - Border set CornerRadius

Hi,

I've a content control with a Border inside. I have to use this control to make different corner radius in a toggle button control (only left corner, center and right corner). To do this I've make 3 differente controltemplate because the CornerRadius of border don't accept a TemplateBinding for that.

It's possible to make an unique controltemplate and passing the corner radius as TemplateBinding?

Thanks
