Is it possible to deselect freestyle edges? Is it possible to deselect freestyle edges?

For example, I enabled Material Boundary in Render layers &rarr; Freestyle Line Set &rarr; Edge Types to draw lines on all edges between faces with different materials:





Is it possible to explicitly exclude an edge from freestyle drawing so I can have all material boundary edges drawn except for ones I specify?

e.g:
In Edit Mode select the edge and Mark Freestyle Edge Ctrl+E,F
In the Properties window > Render Layers > Freestyle Line Set:


Enable Logical AND.
Enable Edge Mark and the (Exclude Edge marks) X button next to it.
