Mon - Each row of the batch reporting configuration file specifies a combination of file recipient, channel and also the template IOK file to refresh and deliver.
File output blocks can be used to timestamp each template IOK file individually. Unfortunately, currently you need to first output the timestamped IOK templates, then manually edit these template file names in the batch output configuration file, since the file names are changed everytime the timestamp is changed in the File Output block.
I have reclassified this as an idea to have the Batch Output operation add the timestamps to the template file names so as to eliminate manual editing and keep the template IOK files names consistent with the continually updating timestamps. This will not be difficult to add.
