Our small firm is in the process of moving to Zoho for PM purposes.  As part of the move we are exploring the features of Zoho Desk.  

We are a re-seller and implementer of accounting software.  Our clients are in diverse industries and the software can be customized in millions of ways.  As a result, even clients in the same industry may need separate instructions on how to perform a certain task.  

Is there a way to tailor the knowledge base for a particular set of client users?  

For example, some of our clients are Catholic Diocese(s).  Is there a way to have a separate set of Knowledge Base articles for each particular Diocese at the overall client level?
