Autoload custom toolbars (partial CUI files)

Hello, 
I need to autoload custom toolbars (partial CUI files) on BricsCAD startup when installing a plug-in.

The plug-in has an installer, so any of these solutions could serve:
  • In installer process write something in Windows registry so BricsCAD load a CUI
  • In plug-in load (NETLOAD) moment load the CUI using .NET API
Thanks
