IsNotBusy Binding?

I often find myself needing to set the visibility of a UI element to something like, "IsNotBusy" (Save Button should disappear when the page IsBusy for example)

   savebutton.SetBinding(IsVisibleProperty, (not)"IsBusy");

I have been creating a property called IsNotBusy and binding to that, but it feels clunky.

Is there an easier way to set the visibility to "not" IsBusy" ?
