Output EPS(1) after an $EST step?

All, Is there a way to recover epsilons after an $EST step? The difference between DV and IPRED is epsilon for a simple additive error model. However, with a mixed proportional and additive error model, I can't see a way to separate the two epsilon contributions to DV-IPRED. $TABLE EPS(1) after an $EST step provides a column of zeros, and the NONMEM manual indicates this is the expected behavior.
