Pass Integration Point Number to User-Defined Material Subroutine

  Hi,
  
  Is there a way to access the current integration point number from the user-defined material subroutine?
  
  I see in appendix R that it is accessible to the user-defined cohesive materials model subroutines. However, I do not see how to access it in the standard user-defined material models.
  
  I need to compute higher order derivatives of the shape functions as part of a regularization scheme at each integration point for my material model.
  
  Thanks!
