WELDMENT GUSSETS

I can't seem to create a weldment gusset on surfaces that meet with a radius in the corner.  I tried making planes that meet in the corner but weldment gusset won't recognize them.  I have to add a structural member and trim both ends.  The easiest way would be to just create an extrusion, but I would like it to be in the cut list.  Is there a way to add a regular feature to the cut list?
