Opposite of Fillet, how to do?

Hi guys,

I need to put a groove along an edge of solid model. I know we have Fillet to make the edge round,

but what about the opposite direction?

Of course, I could do a loft cut along the contour of the edge but it would take a lot of sketches and planes...

and I don't want to do that...unless there's no other way around it.

If you see the picture, there's a fillet done along the edge, how do I change the fillet to be concave instead of convex?

I was looking in the Feature menu but couldn't find anything...

Any input would mean a lot to me!

Thanks in advance,

Ken
