How to Save Multiple Rando Forest Model Time series Based on ID

Hi KNIME Commuity,

So I have a workflow for Random Forest regression with time series data and contain around 30k Unique ID and each Unique ID have 12 month data. I create a loop to predict the next month data for each Unique ID.

Now I have confusion how to save the model along with sub model for each Unique ID? so I can use it to another workflow
