Adding example flow folders to the node-red library?

One of the things I'd like to do next with uibuilder is to allow uibuilder templates to include an examples folder that is automatically added to the Node-RED examples library (or some custom library under the same menu, not that fussed) when the template is loaded.

This would close the circle between Node-RED example flows that come with a custom node and the custom front-end code and configuration that comes with a uibuilder template.

It feels like there might be a way to do this already but I can't find it if there is - does anyone know if this is currently possible?
