Automatically expand interface options?

[MinguasBeef]

I have it when I type in a slash command, that it pulls up the interface options for the main panel with

InterfaceOptionsFrame_OpenToCategory("Minguas Suite")

I have subcategories within this panel however, and I always have to manually expand this panel to see the others. Is there any way to have it automatically expand the panel to see the subcategories?

Thanks
