Abaqus - Defining geostatic stresses at later step in Abaqus

Hello all, 

I would like to know how to define my geostatic stresses in later steps, not initially.  I am searching for a command similar to  (*INITIAL CONDITIONS, TYPE=STRESS, GEOSTATIC)  to define the geostatic stresses of the soil layers but at step 2 (not initially). 

Appreciate any answer,

Thank you
