Is it possible to edit the Viewers on a News item?

We are using the "Post Event to Feed Smart Service" and the "Post Comment to Feed Entry Smart Service". The issue we are having is that we post a News item, we tag it to a record and we specify a group as a Viewer on the News item. If we ever want to remove the Group associated to the News item and add another one we cannot.

If we take Appian Forum's ticket system as an example. They published a News item and they tag it to the support ticket Record and the account Record. They also specify our account group in the Viewers for the News item. Let's say that a new Account is created and all the tickets need to be re associated to this new Account. We would lose all the News items that were associated to our records. They could not be re-mapped by editing the Record tag and Viewer groups.
