Is multilevel model with multivariate response possible?

[qdread]

Hi, I greatly appreciate the work you have put into this package. I was curious if there is currently an implementation of a multilevel CAR model, where you have multiple individuals in each area but also multiple covarying response variables per individual. If not, I would be curious if you have any ideas of where to look for an implementation of that type of model. Again thanks very much for your hard work.
