"Adding weights to multi-classifiers base on labels?"

Flake

In multi-label classification, I am trying to increase accuracy by adding weights to several classifiers on different labels.
E.g. I have L1-L5 five lables, and C1, C2, C3 classifiers. C1 may perform better than other two classifiers on L1 and L3, and C2 are better for C5. Hence, I want to assign different weight in this classifier-voting-committee.

My questions is:
Can this be done in RapidMiner?
If yes, any tips or examples?

Thanks in advance.
