how to add pre define filters in Configuring fields

Hi,
The recommended approach here is to set the slice and filters with the UI tools. After that when everything is set and done you can press the save button and the current state will be saved to the .JSON file. Such an approach allows restoring the state and also reusing the templates. Therefore even when you don’t know the correct template you can always get the right one from the tool.
