Moving to Teamwork from Asana

We’ve been using Asana for the past 18 months so the switching costs to Teamwork is high… but we’re frustrated by the lack of a key feature. I’m not sure what it’s called in project management speak but it’s the idea that template deadlines for tasks and sub-tasks change based on the deadline at the highest level. It’s great to create templates and be able to copy them but the hassle of changing the deadline of every task or sub-task seems kinda crazy. We can export to a csv file and use excel to increment the dates and reimport but that seems like a lot of extra work to train people on. Not sure if there are other limitations of Teamwork but this feature seems to be a glaring hole in Asana.
Thanks
