CDFT-CI with background charges

Dear developers,
I am trying to use CDFT-CI to compute the electronic coupling between |D^+ A> and |DA^+> in an e-field arising from point charges. Is there a way to do so with Q-Chem 6.0.2?
Thank you for your help.

I would suggest $external_charges, if you are not planning to have the atoms move. QM/MM otherwise.
