Show/Hide Comments from other Portals

Problem Descrption

I’m currently working on an Ideas Portal for our customers.

We already have one portal for internal purposes (let's call it Internal Portal) and would like to publish some of the ideas created there to invited customers (Customer Portal).

This works perfectly fine setting the visibility accordingly. The only problem is that in the Customer Portal also all internal comments added to the Internal Portal are shown there, too.

This is a problem because internal comments may contain information our customers shouldn't / are not allowed to see.

So what we would need is:

There should be a new setting in the portal configuration (maybe called "Show comments from other portals").
It should be possible to hide/show comments added in other portals that have the same product(s) assigned.

It would help us a lot - properly distinguishing between customer feedback and internal feedback. Like this, customers also only see what they are meant to see.

In the backend however (when logging into Aha!), all comments from all portals should be shown. Best would be to see which portal the comment has been added from.

Thank you and kind regards!

PS: I chose "Yesterday" in "I need it...." because without having this feature, I cannot use a second portal for customers as planned.
