[CONNECT] Show Custom Toolbox automatically

I have a custom toolbox.  It is stored in a DGNLIB in folder X:\ProgramData\Bentley\CONNECT\Configuration\Organization\Dgnlib\Gui.  I can display that toolbox from MicroStation's Tool Boxes dialog (menu Settings|User|Tool Boxes)...

How do I show that Toolbox automatically when MicroStation is started?  Is there a configuration variable I should set, or a check-box somewhere that should be set?

When I first created that Toolbox, it was stored in the Personal.DgnLib, and was displayed automatically.  Why is a custom GUI object shown automatically from the Personal.DgnLib, but is not displayed automatically from another GUI DgnLib?
