Nested numbered lists in published article don't match editor version

When a numbered list has steps within steps or “nested” lists, the editor uses the following hierarchy:

Numbered > Lettered > Roman numerals

Once published, however, there is no nested list hierarchy. All numbered lists, both parent and nested, are numbered lists once published. This makes it hard to differentiate between the parent list and lists nested within it. 

Ideally, the published version would match the editor's hierarchy (Numbered > Lettered > Roman numerals). We can then refer to steps without confusing readers about which we're referring to.
