Resource registries Plone 5: ++plone++ namespace and overriding single resources

I believe, it should be possible to create the overriding path manually with BTreeFolder2 and File objects through ZMI at

portal_resources/resource_overrides/manage

into

portal_resources/resource_overrides/static/components/tinymce-builded/js/tinymce/langs/it.js

And you should be able to confirm if it works by refreshing ++plone++static/components/tinymce-builded/js/tinymce/langs/it.js.
