Is it possible to perform partial bookmarks sync? Let's say, bookmarks from machine A that are synced to the server completely would be then synced from the server to a bookmarks subfolder on machine B, is it possible? The rest of the bookmarks on machine B would need not to sync to the server in such case. Alternatively, both machines sync to the server but the user would need to specify which bookmark sections (folders) need to be synced and which not, thus avoiding duplication and maintaining consistency.
