Currently during the sustaining receipt generation process a campaign must be selected from the list of campaigns that use the receipt template you are working on.  In our case we have dozens of different campaigns that use the same receipt and will have the same messaging to the constituent when the receipts are issued.  So this means we have to generate dozens of blocks of receipts as well as set up and send dozens of email messages to get the receipts out.  It would be much simpler for us if there was an option to select all campaigns during the generation process and have it create receipts for all donations to campaigns that utilize that particular receipt template.
