Training and Centre of Expertise
Each agreement could have a training center or a tactical research center where more experienced members share their strategies, tactics, and advice. The agreements could also develop young common players who could then be loaned to the clubs of the members of the agreement. A mentoring system could allow experienced managers to train newcomers, thus creating a learning network within the agreement.

It already exists in a lot of agreements.

Why not make a cdf for the agreement whose players will come from the clubs of agreement and will be managed by the coach

Being a selector already requires a lot of time and attention if you do the job seriously... If in addition they have to manage a CDF^^
But since you are overflowing with ideas and imagination with each passing day, you should put your talents to solving real problems, such as climate change, the dumbing down of "modern" civilizations, the preservation of biodiversity, the pollution of water, air and soil etc, etc rather than focusing only on a minimal game without any importance on the scale of life.

Mais vu que tu débordes d idées et d imagination chaque jour qui passe,tu devrais mettre tes talents a la résolution des vrais problèmes,comme le changement climatique,l abrutissement des civilisations "modernes",la sauvegarde de la biodiversité,la pollution des eaux,de l air et du sol etc,etc plutôt que de te concentrer uniquement sur un jeu minime sa
