Importing Object into a container field?

[Zcast]

Not sure if this is the right area, but here it goes. I have a grouped set of buttons that I have given an "object" name of "menu". I also have a container field named menu. Is it possible to place into that container field the menu object that I have on a seperate layout? I know you can place an "outside" object, but can you do the same with a true object from the same file?
