It used to be coded as post processing of the Phonon code but not any more. It should be possible to compute the change in macroscopic polarization induced by a deformation by the Berry phase approach. Or calculate the stress induced by a finite electric field [see e.g. Umari, Pasquarello PRL 89, 157602 (2002)]
