If this is a standard format for your dates, you could create a formula that would parse the string from the reverse side. You would capture the last 4 digits as the year, the next 2 digits as the day, and remaining as the month. Then reassemble them into the format you want including the slash (/). You will find a discussion of how to do this in the CR Help file under Functions->Strings, then look at the Mid and InStrRev functions.
Hope this helps.
