I think you will find, as I did, that most people will regard DX as a visualization tool, rather than a data manipulation tool. Why don't you just write a post-processing routine to add an additional set of data points on the boundarys of the grid cells with values equal to the cell centered value?
Or if you don't like that idea, use the values in neighboring cells, calculate a slope for your "volume averaged data?" and store say the mean of the projected values (from left and right) at the grid cell corners, or nodes. These are just ideas which I would try first, second, third, etc. even 100 before re-writing my numerical integration scheme.
