[R] passing known medoids to clara() in the cluster package

I have had good success using the clara() function to perform a simple cluster
analysis on a large dataset (1 million+ records with 9 variables).
Since the clara function is a wrapper to pam(), which will accept known medoid
data - I am wondering if this too is possible with clara() ... The
documentation does not suggest that this is possible.
Essentially I am trying to implement a "supervised classification" of numerous
geographic data layers. The "unsupervised" approach using clara() works well,
but I feel the output classes would be more meaningful if I were able to let
clara() know about the classes that I have in mind.
Is this at all feasible, or am I trying to accomplish something that is not
