Pari Valueset

Hi all,
       I already have one value set provided by oracle.It is a PAIR value set.  I use that value set for selecting account from and account to.

   Now i want to create a new pair value set with a condition that it should show only values in segment4 starting from '4%'

  I googled it but i could not find the related solution.
