Add Samples to an Existing Batch

I had a very long run and wanted to check the data so I created a batch that included only the samples that had run up to that point. I now want to add the remaining samples to that batch file and am stuck. Chemstation Help says that the option to Set Up a Batch only appears the first time you load a batch for a specific data set. I tried deleting the (partial) batch I created to see if I could get the Set Up a Batch table again ... no luck. Any ideas?
