Today it is not possible to auto-publish a certain user personalization to new uses in D365FO that will be added in the future. You can only copy this to the users that is already in D365FO.

We would like it to be possible to do this in the same way as we publish views to certain security roles, so that the user personalization we have set up to be published will automatically be the default personalization for the new users in the different security roles.
