Ideally customer should be able to opt in/out of different lines of business in a hierarchical manner when a company has many lines of business e.g. NFP works with the community in many ways - each line of business wants a more fine grained subscription than just all in or all out

So I could subscribe for Supported Living and Pre-School - then within that confirm what level of info I want rather than being all in/all out or having to tick 10000s of boxes
