dynamic_search:
    context:
        default:

            relation_management:
                -
                    class: Car
                    relations:
                        -
                            name: parts 
                            options: []

This will add an Eventlistener to the Car Object (preUpdate) which adds all relations (Only the configured ones from dynamic_search.context.[...CONTEXT].data_provider.options.always) from the given property parts to the DS queue (Within the postUpdate event!)
