How to do Multi-step analysis for time dependent inlet boundary condition

Hi,

I am trying to carry out an oscillatory laminar plane flow analysis subjected to a pressure gradient. I have inlet boundary condition for pressure as follows-
Step 1 : t < t0 : P = 5
Step 2 : t> t0 : P = 15*Cos (w(t-t0))
How can I create my inlet boundary condition to be time dependent with specified steps for applied pressure as mentioned above? Your help is very much appreciated.
Thanks.
