Wet performance per team

Is there a way to overwrite the tracks wet weather grip (desc89) in the team performance magic data so you can have differing wet weather performances for teams or even drivers? Some teams always seem to get it right when it rains (Jordan and Stewart and most backmarkers always seemed to be good for that), and some always seem to get it wrong (Ferrari). Likewise drivers like Schumacher/Hill/Alonso/Lewis/Max always excelled whereas Massa/Villeneuve (who were normally pretty good) would just be nowhere when it rained. It would be nice to be able to simulate that kind of anomaly performance for wet races.

Yea it would be great if SDI makes more desc values to be car-dependant in the future
