Easiest way to move ‘Secure Notes’ in Keychain Access from ‘login’ to iCloud?

I want to move, or at least copy, numerous items under Secure Notes in Keychain Access.app from my “login” account (local) to my iCloud account. What is the easiest way to do this? I know I can’t simply drag and drop them.

I have found that selecting some items, pressing Cmd C in login, then going into the iCloud version and pressing Cmd V seems to work but it means having to enter one’s login password for every one of them. Is there a more convenient way?
