Hiding meta boxes in Easy Blogging for custom types

I have created a custom type called "Assignments", and a custom role for it called "Teacher".

So I want teachers to add assignments through the custom type interface. However, that interface is cluttered with too many meta boxes and, in Easy Blogging interface, I cannot hide them.

In Easy Blogging configuration I can hide meta boxes for Post and Pages, but not for Custom Post Types.

Is there a way to tell Easy Blogging to hide meta boxes for Custom Types?

Thanks in advance :smiley:.
