Try using Views Argument Substitutions


  Contextual Filters allow a View to be filtered based on arguments
  passed via URL or other embedded method (e.g. the View Reference
  module), but contextual filters are inflexible compared with normal
  filters (which allow for "contains," "begins with," "ends with,"
  etc.).
  
  This module allows contextual filter arguments to be used as
  replacement tokens in filters and table arguments, so that passed-in
  arguments (such as from URLs or View Reference fields) can be used as
  values in normal View filters.
