[MicroStation CONNECT Ed. U13] MS_DGNAPPS

The <MS_DGNAPPS> configuration variable is predefined and filled with following string: "$(IP_IPLOT)\bin\iplotn.ma;CifDWGExportManager;Bentley.StatusCursorPrompt" on system and application level.

In order to optimize the licences in use of our organization I have to cut  "$(IP_IPLOT)\bin\iplotn.ma;" on  workspace level. 

How can I do this in my workspace.cfg? Which function should I use?

Alternatively is there a way to immediately unload applications after the startup of MicroStation CONNECT?
