For my marketing agency it would be really helpful to be able to use "Projects" as the Client name and then "Lists" be the various marketing areas, which have different needs in terms of tracking. To be able to do this the way I need to the columns would need to be customizable at the list level and not only the project level.

For example if I have Client #1 as my project and have lists for content creation, or site maintenance, etc. I have to use the same columns, which makes no sense.

What I need is this:

Project #1

--List #1 (custom columns)

--List #2 (custom columns)

--List #3 (custom columns)
