Lazy Loading Web-services container for TreeTable

This may have been addressed in another topic, but my product is using a Web Service as its data source on the backend. We are also using a TreeTable to render data on the front end. From my research, it doesn’t appear that LazyQueryContainer can be used with TreeTable. If that’s the case, is there any at least partly developed lazy-loading web services-compatible container that can be used with TreeTable? Or do I have to write it myself (which is not desireable)?
