To access the Style guide settings, navigate to the Production tab and choose "Style Guide" from the menu. Hover over a Style Guide and click ‘Edit’. Select 'Non-Select Assets' in the left-hand menu.
Here, you can set up the naming convention for the non-select assets. This setting is only active if on your workflow level the 'delivery non-selects' is enabled.
The default naming convention for non-selects is '_non-select-ProductCode'. To add/edit the naming convention for non-selects, click in the text field and/or select one or more properties to define the output name. It's required to use the property 'ProductCode' in the output naming. After setting up the naming convention, click ‘Save’.
