How Can I Color Dendrogram Branches not according to their clusters

I am using the Matlab dendrogram command:

Y = pdist(data,'cityblock'); Z = linkage(Y,'average'); [H, T] = dendrogram(Z);

I am familiar with the 'ColorThreshold' option but I want to color branches based on their original attributes and not based on their clustering. For instance if columns 1,5,8 in my original data matrix were all of type 'A' I want their branches to have the same color in the tree.

Is this possible?
