Multilevel Bayesian Causal Forest

[pvg257]

Hey, I am interested in estimating a multilevel Bayesian Causal Forrest as used by Yeager et. (2019). While the co-authors Jared Murray and Carlos Carvalho have discussed the extension of BCF to multilevel models in several talks and in the supplemental material to the paper, they do not state with which software they estimated their model. Does this package enable one to estimate such a model? Really appreciate the work on this package, and I thank you in advance for your help.
