I think there's a couple ways to do this. Without looking at any data, the first thing that came to my mind was just doing a data source inner join, based on the Batch name field. Would that work? If not, could you post a data set so that we could try and help you out a bit more specifically?
A join as Vincent suggested could work, an alternative instead of a join or data blend would be to use a filter action on both Batch Name (and Start Date if necessary) from your first worksheet to your second worksheet.
