It would be amazing like Service Items, we could add in Requester visibility:
 

We have various different agencies and if we could use the Requester Groups we have created for Service Items as well for Solution Articles, this would make showing the right customers the right Knowledge Articles instead of relying on Tags or creating Folders with different Visibility on the folder per arrangement. This would mean we would have (as we have 5 agencies and therefore would have too many combinations to create that many folders) and therefore have started relying on tags instead but this means that agencies have access to other agencies knowledge and mean that they may follow the wrong instructions.

Having the ability to add the Requester Groups to each article as well would mean we could create a folder called Published Articles and just add the visibility to each article individually as well.
