Hole Note should not display "1 X " if there is only one pattern member

I am using Creo 11. I have separate .hol file. I want to write code in that .hol file so that "1 X" should not be visible in the hole note. Plz help, how can I modify this line

{0:&PATTERN_NO}× /{0:&FASTENER_ID} × {0:&THREAD_DEPTH[.1]}<ctrl-a>/<ctrl-b>{0:&DRILL_DEPTH[.1]}V

so that Pattern_No will not visible if the value is 1.
