Transient Simulation in ANSYS CFX

I am running a transient simulation where the boundary condition is a pressure that oscillates with a cosine function (Womersley flow).
At the moment, I enter boundary conditions as columns (1st column time, 2nd column static pressure) in a data file and import it into a user function.
I then call the user function from the prompt box under B.C>Static value etc.
Is there a more elegant method of doing this? In the current method, will ANSYS interpolate between BC pressure values at each time step, or not?

You can use a CEl expression. Something like:
Pressure = 100 [Pa] * cos(t/1[s])
