Sharing a layout with a user in another user group

Is it possible for a user to share a layout/media with another user who is in another user group?
They only seem to be able to modify permissions for users in their existing user group

Thank you for your message. You will need to use a Super Admin account to have access to the full range of Permissions for all Users and Groups on a Layout or Media Item. When logged in as a Super Admin, you will be able to set the permissions for that User in another group.

Many Thanks.
