JSFL - enterEditMode after convertToSymbol?

programming flash
1

I’m adding tons of ‘Groups’ to the library using:


var allElements = fl.getDocumentDOM().getTimeline().layers[0].frames[0].elements;
var selectionArray = new Array;
for(var i=0;i < allElements.length;i++){
     fl.getDocumentDOM().selectNone();
     selectionArray[0] = allElements*;
     fl.getDocumentDOM().selection = selectionArray;
     if(allElements*.elementType != "instance") // Leave  MCs alone
     {
          // Add symbol to library (with default name 'instance1' etc.)
          fl.getDocumentDOM().convertToSymbol("movie clip", "", "top left");
 
/*
How do I:
1. Enter editMode on newly created symbol?
2. Add new layer in symbol (as the bottom layer, as I'm trying to expand the clickable area below a letter shape)
3. Draw rect, something like this ...
     newly_added_mc.addNewRectangle({left:0, top:0, right:st.width, bottom:st.height}, 0);
     newly_added_mc.selectAll();
     newly_added_mc.breakApart();
     newly_added_mc.setFillColor("#000000");
     newly_added_mc.setStroke("#00000000", 1, "solid");
     newly_added_mcselectNone();
     newly_added_mc.exitEditMode();
*/
    }
