It would be very nice if the "Ignore text field", which is available in Device.Backup.TFTP, Report.Compare.Two files and Report.Compare.Running Startup (could be in other jobs too, but those are the ones i found) could be implemented in the "Device.Backup.Running Config" job. Often there are certificates or other things that varies that we would like to be able to "ignore" when changing, so not to generate a config change report for each and every run.
