How to define Boundary Load dependent on both region.x and region.y?

Hi I am designing a Bridge in PDE-toolbox. I want to apply load on different region of the bridge deck. But it seems the the load vector can be either as big as region.x or region.y. Is it possible to apply load on the face in a way which is different for every x and y coordinates?

To apply boundary conditions that are functions of position, see Nonconstant Boundary Conditions.

Hi Thanks for the answer, but I already read that. The definitions are a little ambiguous and also all examples are done with regard to one dimension, namely "location.x" or "region.x"
