[dhtmlxGrid] Drag and Drop styling

I noticed for extended drag and drop, the dragging tooltip always says “message/messages”. I also saw in dhtmlx_extdrag.js the message is equal to (this._dratA || “message”). What is _dratA and how might I set it to have my own string in there without editing the JS directly?
