I've only recently started using Zoho Projects, but I'm very confused that sub-task durations are not rolled up into the parent task duration. Without this, it seems impossible/really hard to work out how long everything is going to take when planning a project from the bottom-up.

Am I missing some way of setting the system to do this? It feels like it should be a standard function for any project planning system, doing some research it looks like people have been talking about this for over 5 years now. :(

Is there any update?
