Hiding columns - sub items

The ability to hide columns on sub items would be really useful. Does anyone know if this is on the roadmap?

If we could hide columns on sub items it would mean that on certain views would focus the users on the right columns, rather than saying collapse certain columns

I am linking several boards in the subitems. Having the ability to hide these columns that feed into the item would make this cleaner and easier to read. Only the people connecting the boards need to see this. Most do not.

We use a board to list all the key users tests for one project.
We call it “cahier de recette” in French.
An item for a user story and many sub-items for each action.
A view for each key user team.
Some team need some sub-items columns not usefull for all other team.
