Hierarchical Clustering and "cluster's number" (not number of clusters)

I perform a hierarchical clustering:

rng default;  % For reproducibility
X = [1 2;2.5 4.5;2 2;4 1.5;...
    4 2.5];

Y = pdist(X)

Y = pdist(X)

squareform(Y)

Z = linkage(Y)

A =cluster(Z,'MaxClust',2:3);

The problem is that the cluster's number of the clustering with 2 clusters is not consistent with the clustering with 3 clusters: all cluster's numbers have changed (the same is true with 4 or 5 clusters...) Is there a way to solve this problem or to easily re-index the clusters in a consistent way ?
