How to share solution of problem I solved when original threads did not solve problem but are all locked?

There is an issue with copying contacts in MacOS 26. The issue I have now is that the problem has persisted for a while (years) and several people have had the same issue that I had, but the discussions have all been locked so I don't know how to post the simple work-around.

The problem appears when you are trying do duplicate a list from iCloud on a Mac running Tahoe. When you do a simple <command-a> on "All iCloud" and then try to create a new list using "create list from selection" or dragging it to another list it fails. The work around is to first deselect your own card -- My Card -- from the selection. Is there a way to add this solution to the community?
