There is a new (and undocumented) feature in the ISL that allows you to 
automatically
change the file (or files) used by a data source.

The bundle tag can contain any number of "setfiles" tags.
Each of these setfiles tags has a datasource attribute which is used
to find the data source in the bundle by name. There is also a file
attribute which defines a file to use for that data source.

e.g.:

<isl debug="true" offscreen="false">
  <bundle file="test.xidv">
     <setfiles datasource=".*" 
file="/upc/share/testdata/grid/netcdf/nuwg/ruc.nc"/>
  </bundle>
  <image file="test.png"/>
</isl>

This bundle above only has one data source. The datasource=".*" identifies
the data source by name. In this case it is a regular expression that matches
anything. If you had multiple data sources you can change their name before
you save the bundle (right click on the data source in the field selector and
got to the Properties dialog.) You can then use these names to match. e.g.:

<isl debug="true" offscreen="false">
  <bundle file="test.xidv">
     <setfiles datasource="datasource1" file="file for first data source"/>
     <setfiles datasource="datasource2" file="file for 2nd data source"/>
  </bundle>
  <image file="test.png"/>
</isl>


If you have a data source with multiple files (e.g., radar) you can use an 
embedded fileset
tag. More here: 
http://www.unidata.ucar.edu/software/IDV/docs/userguide/isl/FileTags.html#fileset

   <setfiles datasource="datasource1">
      <fileset file="some file"/>
      <fileset file="some other file"/>
   ...
    </setfiles>


I hope that helps.
