this multilight feature is great, but if you have an architectural scene you want to render by night, you need really a lot of lights.

if you then have to control every light, it´s not workable.
so you put some of them into one object, in order to have light groups you can handle, but the intensity option "w/m²" is not there any more which would be useful to set up the lights nearly correctly.

in my eyes this would be better than setting thew emitter intensity up to 20000w.
