I was hoping this would happen internally since it doesn't make sense for the linear solver to start the iteration cycle with a zero guess when one could re-use the computed solution on a coarser mesh to get an estimate of the solution on the finer grid.
I tried this a long time ago and it turns out that it doesn't make much of a difference to start CG with the interpolated previous solution.
