Use the "Applies to" filter to target the data source at components which have fragments or decorators. A catalog entity will have an additional annotation called "roadie.io/applied-fragments" when a fragment or decorator has been applied.

We recommend starting with a highly targeted filter for initial experimentation and iteration. You can widen the filter later to capture more results.

Click the "roadie.io/applied-fragments" annotation
