Directement dans InDesign, ça dépend du niveau de précision du CdF que tu veux obtenir. On peut jouer avec des séries de blocs ancrés qui se décalent au fur et à mesure de l'insertion de pages, mais ça reste de la bidouille.
You can do a flatplan (chemin de fer) with InDesign either with miniatures or a schematic one (I append images of both).

However, in March 2020 the whole team of the magazine I work for were forced to work from home (guess why) and aside from using Slack and a VPN connection to our servers we managed to make our deadlines thanks to a website that offers a flatplan service called Blinkplan that made our life so much simpler and easier that I recommend it very heartily: https://www.blinkplan.com/ (I have no other relation with them but our clientship and there are some other similar sites).
We don't you give it a try (I think they have like two weeks free trial)?
