Importing graphic into graphics frame on a Reference page

Hello All,

Need to import a graphic (by copy) into a graphics frame located on a Reference page of the document. The objective is to have a number for each chapter on the First Master Page. This is done by using 'Frame Above Pgf' of the Paragraph Tag. This works fine manually, as shown below. I would like to have a generic chapter FM file where I can change the chapter number according to the value of <$chapnum>.

Is there a way to import the graphic (number) into the graphics frame? I see Import, but it requires a TextLoc that I don't have.

Any help is greatly appreciated.

#target framemaker
var oDoc, oPage, oFrame, oGfx;
var oDoc = app.ActiveDoc;
if (oDoc.ObjectValid()){
    //
    oPage = oDoc.FirstRefPageInDoc;
    while (oPage.ObjectValid()) {
        alert(oPage.Name);
        oFrame = oPage.PageFrame;
        if(oPage.Name == 'Reference Page 2'){
            oGfx = oFrame.FirstGraphicInFrame;
            if(oGfx.ObjectValid()){
                while (oGfx.ObjectValid()){
                    if (oGfx.constructor.name == 'UnanchoredFrame'){
                    alert(oGfx.Name);
                    }
                oGfx = oGfx.NextGraphicInFrame;
                }
           }
        }
        oPage = oPage.PageNext;
    }
}
