vertica error "The [TimeSeriesModel] [tag] in [PMML] is not supported yet"

Hello,

Can someone from vertica dev team confirm that importing time series model PMML not support yet? I got following error message when try to import arima model (export from statsmodels) to vertica.

dbadmin=> SELECT import_models('/tmp/pmml' USING PARAMETERS category='PMML');
