Parents of parent aren't accessible

When working with localization it's often the case to have the same structure for multiple objects which you want to 'merge' when exposing to a third party. For example object 'attribute' and object 'classification' both have a code but the name is localized.

Attribute object:

{
	"attributeCode": "unique_attribute_code",
	"localizedAttributes": {
		"en": {
			"attributeName": "HP",
			"formattedValue": "100 HP"
		},
		"de": {
			"attributeName": "PS",
			"formattedValue": "100 PS"
		}
	}
}

Template object:

        content: {
            classificationCode: { dataKey: 'classification.code' },
            attributeCode: { dataKey: 'code' },
            localizedAttributes: {
                dataKey: 'localizedAttributes',
                content: {
                    nl: {
                        dataKey: 'nl',
                        content: {
                            classificationName: { dataKey: 'Cant get classification.localizedAttributes.nl.name' },
                            attributeName: { dataKey: 'name' }
                        }
                    },
                    fr: {
                        dataKey: 'fr',
                        content: {
                            classificationName: { dataKey: 'Cant get classification.localizedAttributes.fr.name' },
                            attributeName: { dataKey: 'name' }
                        }
                    }
                }
            }
        }

As you can see in the template I can set the attribute code and go deeper on the object for the classification code. But for the localizedAttributes I can't use classification.localizedAttributes.nl.name for example. And I can only climb up one parent with the source parameter.

It would be great to extend the source parameter to chain parents here. For example:

    content: {
        classificationName: { dataKey: 'name', source: 'parent.parent.classification.localizedAttributes.nl' },
        attributeName: { dataKey: 'name' }
    }

This way it's possible to go deeper and higher with ease and gives so much flexibility for building custom views.

I don't have much time to work on this project. But I think it is fairly easy.
Would you please send the payload, so I can test it thoroughly.
It will be more like:

content: {
        classificationName: { dataKey: 'classification.localizedAttributes.nl.name', source: 'parent.parent' },
        attributeName: { dataKey: 'name' }
    }
