Electrostatic Potential/Electric Field mapping using Classical Charges

Is there is a tool in Material Studio that can take a periodic system containing a set of atoms with atomic charges, and output a 3D electrostatic potential/field for those charges?

I'm aware QM software like CASTEP/ONETEP can do this, but I'd like to output this from a classical forcefield. It could be calculated via Ewald sum (ideally) or via any other method.

Kind Regards,

Ben
