Objection.js Syntax for INSERT INTO ... SELECT

Question

The datastore is postgres. Can someone help in translating this to an Objection.js statement? It's easy to do this with two roundtrips, but ideally this would happen in one.

INSERT INTO reports (
    id,
    created_by,
    desc,
    dataset
)
SELECT 
    '8971e660-7777-4d64-8cc3-171512063fff',
    123,
    'clone!',
    r.dataset,
FROM reports r
WHERE r.id = '7771e660-9d7d-4d64-8cc3-17151206354f';
