Currently, subtask date sync can only be enabled per List or per task. If you manage a Space with many Lists (and regularly create new ones), you have to remember to turn this on every single time. It would be much better if we could enable subtask date sync as a Space-level default so that every List (existing and future) in that Space inherits the setting automatically. Power users managing complex projects with lots of subtask hierarchy really need this to avoid manual repetition and inconsistent behavior across Lists.
