No, I don't think so. Because IMHO you can do your request with almost no effort from the current snippet feature. Just tick all boxes in the snippet creation window, especially the edit after creation box and you can immediately add the snippet to an existing (or new) setlist even without much editing.
To automate that last step is overkill IMHO for a very specific user case scenario. Just my 2p though.
