Independent people column to board members

Sometimes we need to make a relationship between some people in the organization, but we don’t want that person to be a member of the board or be able to see this information.
This is useful for handling information and evaluations etc. and not necessarily to assign tasks to the person.
Using the text column does not allow you to filter the info in a friendly way.
I think that this problem would be solved if there was a column of people of the organization where you can choose several people without them being part of the board. Or that the column’s custom settings of people can be set as task assignments or just information.

We would definitely find the feature beneficial
