About unit in x and y axis of 3D plot in Prime 2.0

Does prime 2.0 not allow unit in the variable for x and y axis??

suppose I have

f(x,y) := x*y/10 m^2 + 100 m^2

and the unit in x and y are both meter^2

then I cannot plot f(x,y) in 3d plot? Nor can I use it in creatmeash? not even with the matrix builtin function because it only take unitless value for the range ???? What good is 2.0 then...

I just hate the process of dividing all my variables by their units ........
