[R] feature weighting in randomForest

Hello !

I´m using randomForest for classifacation problems. My dataset has 21.000 observations and 96 predictors. I know that some predictors of my dataset have more influence to classify my data than others.
Therefore I would like to know if there is a way to weight my predictors. I know that for constructing each tree in a forest the most influencial predictor is used for partitioning the data. But maybe it would have an effect if I weight my predictors. 

Thanks in advance
