Default Wall velocity changing with position

I have a simple rectangular channel. Fluid is flowing through this channel. I need to define the upper and lower walls of this channel to be in motion. But I want the velocity of walls to change with the position in channel.

In other words, I want to define the wall velocity as a function of position.

Is it possible to do that thru the use of UDF?

Thanks.
