Would be great to have an option to create Group templates

I want to use Groups as features. Each feature has the same development stages, say Design, Pre-Production, Production etc - that I create as Projects within each group.
To avoid manually creating the same set of Projects for each new Group/Feature, I would like to have an option to create a Group template and copy it every time I add a new feature/Group to my board, so all the Projects within it are created by default
