  you could do something like this:

    any::
        { /tmp/f
          ReplaceAll "[[:digit:]]{2}[[:alpha:]]{3}[[:digit:]]{2}" With
"$(day)$(month)$(year)"
        }


but cfagent will complain that it is non-convergent since the string
you'd put in place will always match the regex so it will get re-edited
every run.  if you know that all of the date strings in question are
of a certain year or have some other static characteristic you could
put in the regex, it might work.  note that $(year) is a four digit
string.
