Not sure if this is a feature request, or something that can already be easily done. I need to do a file transmission of a file that has a filename that is a hex number incremented by 1 each time it generates. I would like to be able to validate that each time the job transfers the file, that there has been no skip in the sequence number - i.e. no files have been missed or skipped. In other words, the filename is already generated by another application, but when the job picks up the file, I want to validate that the hex sequence number in the filename is the next expected sequence number - that it can store the previous hex sequence number from the previous file transfer, add 1 to it, and validate that the next file sequence number that appears is the correct sequence number. (I have jobs that do something like this for regular sequence numbers, the difficulty here is that for this file, it's a hex sequence number, so I can't use same VisualCron function to do this.)
