Brain,
      The problem is that there are several steps in the loading display only 
bundle can go wrong. It is probably easier to save a regular bundle, and then 
change the data path.
      In general, it is always the most challenge part to do the perfect design 
of the user interface in a application like the IDV. We welcome any suggestion 
to improve the user interfaces in the IDV. The development of the IDV is always 
driven by the requirement of our community.
