Adding point charges to the molecule

Dear Psi4 users,

Hi, I have a question about placing point charges to the input file.

I have a specific xyz coordinate of point charges and want to place it while doing DFT or DMRG calculations.

Is there any way to put them in those calculations?

Thank you for the help

Does this test case help?

Thank you for the reply.
I guess this is what I looking for. Thank you!
