Roof edges - Why are not like the Slab Edges options?

[FBernardo]

Hi all, 

I've come across this a long time ago but i always forgot to ask about this, 

 

I've been doing some roofs where i want the top component to extend to meet the gutter, usually tiles, but while using the EDGE function inside the Roof style tool, this creates the edging all around the Roof or on a single side of the Roof Face (and if you have an "odd" shape roof the roof face single side edge doesn't work, as it only applies to one (please see images below it's almost like an L shape), and if i want to show on both edges on the same side, i have to slip the roof face in two... This makes it counter productive and honestly not functional at all.

 

Now my question is, is there any function that i'm missing that can treat the edge of the roof like the edge function of the slabs? If not is it possible to include that in the roof and roof face tool??
