Hey @rsanga,
Thanks so much for this information - super helpful and I can definitely see where you’re coming from here, particularly the tediousness of adding new tasks back to the high-level board each time it’s created.
I believe your request aligns closely with this request here → Mirror Column - Select Entire Board or Group. If this is the case, this is a feature that is currently under consideration and I’d encourage you to add your vote to put greater emphasis on this need
