Granting view/manage permissions for one column

[#1]

I would like to be in a position where I can define the job role who can edit columns in a report.

For example:

I have a report with 10 columns. So I would like to give edit access of first 2 columns to PMs and view access to rest of the columns. Then I would like to give edit access of next to columns to engineers and view access for rest of the columns.

Right now WF doesn't support such capability. It will be really helpful if we get such capability in WF.
