A batch should be ordered as desired. Currently the order is given by the sequence the patrons are entered into the list. That sequence is not shown again but defines the arrangement of the patroncards on the sheet. Staff trying to hand out new patron cards need to find these on the sheets. Staff would really appreciate if there was a reliable and obvious order. Implementing ordering has nothing to do with the current feature that batches can be displayed ordered according to currently shown names or card numbers. The display feature is helping to check the batch but is not creating order on the sheets. Implementing ordering should start with entry order but should allow to reorder list items, e.g. to shift a patron that was missing initially and added later into the desired position. Ordering by barcode or by surname are other likely choices.
If patron barcodes are used for the list of patrons in a batch this modification can be simulated by entering the barcodes in desired sequence. Preparing a list of barcodes and ordering it as desired could be done externally using a spread sheet, e.g. calc. I have no idea how to produce a list of patron numbers with the desired ordering.
