Actually, just realised it seems like this is possible.
The issue is that is entirely not obvious how to do it. Little bit like needing to hold the CTRL key down to select multiple texture filters. The functionality is there but most people aren't going to figure it out without wasting a lot of time. I guess there are two approaches.
Increase available documentation. Current vids/articles don't really do H2N justice at this stage.
Make some of the features more obvious so training content is not required.
