Looking for a multi-level mixture models

Hello all,
I am looking for an R package that can implement multi-level finite mixture models with more than 2 levels (at least 3 levels).

I know flexmix() can implement repeated measure but that's about it.

Any suggestions and/or resources would be greatly appreciated.

Best,
