Pls add feature to get the item name of list along with id after serialization.

Current Output [{"id":13},{"id":14,"children":[{"id":6}]},{"id":15,"children":[{"id":16},{"id":17},{"id":18}]}]

Expected: [{"id":13,"name":"Item 13"},{"id":14,"name":"Item 14"},{"id":15,"name":"Item 15","children":[{"id":16,"name":"Item 16"},{"id":17,"name":"Item 17"}]}]

Thanks
