Redmine

Hello,

In my company we have a Redmine shared with some partners, we are working on projects with them to implement some features on our products for specific customers, etc.
We discuss with our partners in the History of the issue by adding notes and they respond.

Actually we want to give access (in restricted view, no edit) to our customers their projects but we don't want customers to see the discussion with our partner, so disable the Issue history for them.

Is it possible by any way to do it ?
I think it would be great to implement this in the "Roles and permissions" as there is already an option for hiding Wiki History to a role like in the screenshot attached.

Thanks !
