Map slot for the refraction fog color

Hello Chaos guys,
today i worked a lot with a VrayMultiSubMap, addind different colors to different IDs to the refraction slot.
What i really miss is a map slot option for the fog color and possibly trength so i could instance the refraction map to the fog color.
Hope i made myself clear enough so its understandable..
Would it be too hard to implement this?
Thanks for your reply
