title: docFX - Remove namespace prefix in API Reference TOC
body: <p>I am generating API reference from C# project.
  The project is part of big solution and has long name convention for assemblies and namespaces, so every namespace in project goes like [CompanyName].[System].[Area].[Module].[...] (e.g. MyBiz.CRM.Sales.Analytics.Persistence.Common and MyBiz.CRM.Sales.Analytics.Persistence.Sql). 
  Since all namespaces in project start with MyBiz.CRM.Sales. and I generate reference for each system and area separately, I want to exclude MyBiz.CRM.Sales. in TOC on left side and only mention it in title/header.</p>
  
  <p>Is it possible in docFX or I need to write custom server side post-build event script?</p>
  
  <p>Thanks in advance</p>
