I am new to WPF. I have created a user control and using it at multiple places like this

                <DropShadowBitmapEffect Color="Black" Direction="180" Softness="0.25" ShadowDepth="1" Opacity="0.5" />
I want to know if there is any way to define this at one place and use it at multiple places, so that when I want to change the parameters - I only need to change it at one place.
