Custom controller based on base controller class

Hello Radzen team,
Is it possible to create a custom controller based on a base controller?
With reference to the attached files I created a copy of your default ServerMethodsController.cs ,ServerMethodsController.cs based on a base controller BaseServerMethodsController.cs
However Invoke custom method does not show ServerMethodsController2 although it does display the base class.

Indeed at the moment Radzen will list only classes whose base class is "Controller" - the default ASP.NET MVC base class.
