Question: Adding tick marks a 3-D plot of a matrix: letters on x and y axes but real or integer numbers on z-axis

I wish to add tick marks to a 3D plot of a matrix.

B:=Matrix(10, 10, [[0, 0, 0, 0, 0, 0, 0, 0, 0, 1], [0, 0, 0, 0, 0, 0, 0, 1, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 1, 0], [0, 0, 0, 0, 0, 0, 1, 0, 0, 0], [1, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 1, 0, 0, 0, 0, 0], [0, 1, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 1, 0, 0, 0, 0], [0, 0, 0, 1, 0, 0, 0, 0, 0, 0], [0, 0, 1, 0, 0, 0, 0, 0, 0, 0]]):

Below, I draft a plot of this adjacency matrix B . I have adjusted  the position of the domain graph ticks for the x and y axes to be letters at the midpoints of the matrix elements:

tickList := [1.5 = "W", 2.5 = "P", 3.5 = "K", 4.5 = "C", 5.5 = "Y", 6.5 = "F", 7.5 = "X", 8.5 = "H", 9.5 = "T", 10.5 = "E"];

tickmarks = [tickList, tickList, tickList];

matrixplot(B, axes = [0 .. 12, 0 .. 12, 0 .. 12], heights = histogram, axes = boxed, title = "Above adjacency matrix B - axis order 1-10 \n Basis set: {W,P,K,C,Y,F,X,H,T,E}", labels = ["from", "to", ""], orientation = [0, 0, 0], tickmarks = [tickList, tickList, tickList]);

BUT I would like the z-axis not to be the above letters but instead the real (or integer) values of the matrix elements.  How should I do this, while retaining the x and y axes labels as letters located at the ticklist above.

Please can someone help?
