Not currently @Jean1 with one of the recent releases we did add in the option to use oneWay or manyWay relations to the Admin panel users but those fields will not show up on the actual admin model (as it’s not required). You could for the time being create a model to hold this day with a relation to that (admin panel admins model) but until the strapi-admin package is moved to the plugin you won’t be able to extend it without forking and maintaining your fork of the strapi-admin package.
