A model that is marked as as Default will be used by TRIMMR dataset of the same object type automatically.  For objects with multiple models, users can select any model in the dataset configurations (see Configure Datasets documentation for more info).

To set a model as a default, select the model and then press the TOGGLE DEFAULT button.  The DEFAULT label will be displayed next to that model.  You can also un-tag a default rule, using the same process.

Good to know: If no default model is designated then DataGroomr's global default model will be used.
