scikit-learn - Multi-class AUC for GridSearchCV and RandomizedSearchCV

I'm using GridSearchCV and RandomizedSearchCV. I have a multi-class setting with 4 classes and an imbalanced dataset. Currently, I'm using f1_micro as the scoring function. Now I would like to use instead micro averaging of AUC. Is there a possibility to use such a multi class AUC for GridSearchCV and RandomizedSearchCV?
