Column permissions master table

Hi.

I was wondering if there is in the road map something to set the the columns permissions easily.
For example I have multiple boards (with a lot of columns, some of them 20-30 columns) where our team and guests collaborate (the guest usually are different depending on the board, mostly our clients) so setting up the restrictions/permission is critical (as we don’t have a guest see information meant for the internal team only).

I would be nice to have an structure to set the permission like a list of users vs columns with check marks for those privileges (restrict view, restrict edit) the user will have.

Thanks.

Need it too, under so many boards and diferents types of them…this kind of permission would be nice for the management
