Hey all, it's another OnClick JavaScript button migration question!

I've read all the documentation, so I understand the concepts for migration, but I can't find a way of replicating this particular behaviour:

An OnClick JavaScript button that redirects to an edit page (NOT edit modal) of a new record with certain fields pre-filled.

I've got the apex I need already, from the OnClick JavaScript button, but it's the navigation that's causing me issues. Using the best practice lighting:navigation component in a Lightning Action, I can redirect the user to the view page of a new record, or I can open the edit modal for the new record. But I can't redirect to the full-page edit screen for the new record. Is this possible?

The modal is too small and the record has lots of dependencies, so it just looks clearer and cleaner on the full-page edit screen.

I guess we could create the new record and then direct to the view page and train to users to inline edit for the full page, but this seems like a regression to me....

Grateful for any suggestions to improve the user flow.
