Hi
The only issue now is that you cannot have more than one full stop in a filename as Microsoft looks for the first full stop in a filename and then uses wverything after it to determine which application was used to produce the document. Having 4 full stops in the filename will confuse Microsft Word. You will need to choose another separator for the date of birth other than a period or an arithmetic operator.
I will look at the other option you are after.
