Diagram
#1

Hi,
I have created a working dhtmlx. but when i give template to addShape like below defined.

diagramEditor.diagram.addShape("task", {
  template: taskTemplate,
  defaults: taskDefault,
});

then the taskTemplate will be exact the same for left panel and a task added to the back screen. changing one will effect the other
i want to change both template.
like its design should be different for left panel and different for the task drawn.
any assistance in this regard will be highly appreciated.
