The ability to add a column in a SINGLE group without it being forced to display in others.

My request is pretty straightforwards and adds a lot of benefit to the task at hand. I have a board where I manage an operation and in that board I like to manage the flow of different tasks, the only problem I am having at the moment is that every time I add a column to a single group I.E. CRM, it will add that column to every single other group with no option to only add it to that single group. I would really appreciate it if you guys can integrate this into the platform. I believe it will help lots of people with organization and customization in their boards. Thank you!
