Hi folks and apologies for the late follow-up here! We’re indeed working on implementing rules for subtasks. Right now, we’re only experimenting with it and we aren’t planning to roll it out until the beginning of next year.
@Daniele_M all product updates are announced ahead of the release in the private Ambassador Forum category (expect a full post later this week!). Once we officially begin the roll-out we will update and close out this feedback + make an official announcement in News.
I hope this helps, stay tuned for more updates!
