Multi add/mult nodes

So this is probably a 'nice to have' but I think it is worth thinking about as I hope its not too difficult..

I am doing this

half4 cumulative = t1 * color.r + t2 * color.g + t3 * color.b + t4 * color.a;
half4 cumulativeNorm = t1b * color.r + t2b * color.g + t3b * color.b + t4b * color.a;
fixed vertcolors = color.r + color.g + color.b + color.a;

if(vertcolors != 0)
 {

cumulative /= verts;

cumulativeNorm /= verts;

 }
cumulative = lerp(basetex, cumulative, vertcolors);

It ends up looking like this..

:)

Obviously the encapsulated nodes will be useful in the future but..

The  4 multiplies and adds in a row..

Maybe have a grey out extra nodes, they only become available once A and B are used and are obviously optional but an almost unlimited number could then be done in a row..
