Default UDF: for the setting of roughness height

hi,I am dealing with the flow over a roughened surface, I found there is only a option for constant roughness height in FLUENT.

But I want to set different roughness height at different position on the surface. So I wonder if I can use UDF to set the roughness height.

I am not familiar with UDF,so I am posting the message to ask if UDF can be used to set variable roughness height on the wall.

Expecting any suggestions, Thanks a lot!!
