Anyone ever been able to rescale the size of autogen objects?

I just posted a question on the general forum about how difficult it is too see the vector autogen power utility pylons. I tried hand placing a few and found that in order too see them easily enough from around 3,000 - 4,000 AGL, they could be at least twice the size they are now. Maybe they are correctly scaled now, but that doesn't take into account low res monitors compared to real life and a small 2D viewing area compared to real life.So has anyone been able to rescale the size of autogen objects (I mean without individually hand placing them)? There doesn't seem to be any parameter to change the scale of the pylons themselves - only the distance between them.
