Add elements to doc

Hi,

I want to know if this is possible to manipulate fm objects to add existing elements (instanciated objects) to a document.

I saw multiple ways to create doc objects but I can't found any way to add it anything but text.

I saw in the api some functions to create new elements, F_ApiNewGraphicObject(), F_ApiNewAnchoredObject(), F_ApiNewElement()... but none to add an existing element...

Is there a way to do that ? If not is it possible to clone an object ?
