[CONNECT C++] Possible to somehow make a "nested cell" given two EditElementHandles ?

Is there a way to create a "nested" cell when you have two EditElementHandles, when each is a handle to a cell? Is it wise to create a new cell header then use mdlElmdescr_appendDscr() to add in the ElementDescr's from each EditElementHandle? IS there another way?

Thanks
