Ionization PECs?

Hey Curt, I noticed in how ColRadPy calculates PECs, i.e. when I use `colradpy.write_pecs_adf15()`, that the code only recognizes excitation of ion with charge Z, recombination from ion with charge Z+1, and sometimes charge exchange. But, I know that in spectra I'm modeling there's a few very specific but important lines that are purportedly significantly populated by collisional ionization (ground or even innershell) from the ion with charge Z-1 to the excited state of interest. I understand that recombination/ionization in atomic data files are organized by looking at ion Z and its relation to ion Z+1, so I'm not sure how much of an effort it would be to also give ColRadPy the Z-1 atomic data file to calculate ionization PECs. Thoughts on this?
