whether it is possible to set distinct external electric fields for different groups in DPLR.

### Summary

Assign different electric fields to distinct groups of atoms, similar to a regular fix efield

### Detailed Description

The same external electric field is applied to all atoms in the fix dplr command. Is it possible to assign different electric fields to distinct groups of atoms, similar to a regular fix efield? This would enable simulation of additional scenarios, such as the depolarization field of domain structures.
