Gurobi: can you retrieve the dual solution from each node of the B&B tree using callbacks

When solving a MIP with Gurobi, one can use the cbGetNodeRel() function to extract the primal solution to the LP relaxation at each node in the branch and bound tree. Is there similar functionality to extract the dual solution as well? It seems theoretically possible, but I sense that it may be a difficult engineering problem due to Gurobi's extensive pre-solve routine.
