first of all, it seems you mistakenly opened a new support ticket instead of creating a new post in the Ideas forum where we track feature requests.
Secondly, the link you provided is about keeping Remote directories up to date when local files are changing - not the other way around. Although Royal TS doesn’t do this on a directory level, it does it for files opened from a remote location to edit. I can’t find anything which does the opposite. I think the reason for that is the technical difficulties to monitor remote directories in the same way you can do with local directories. Again, feel free to open a feature request and if you can provide an app which can do what you want and if enough other users are interested in it, we can definitely look into it.
