I have just tried some ways to proceed.
With Phocus, you have to create a "scene calibration" / LCC for various lens configurations (focus distance, aperture,...) if you want to have an almost perfect correction of the color cast.
In Lightroom, you have to shoot a blank or grey surface for every picture you want to process for removing the color cast, and you can't save it as a preset.
So, it looks to be very cumbersome, even if less within Phocus than in Lightroom.
Accordingly, I have made a request to Hasselblad if it were possible for them to provide a firmware improvement for the X1D, specifically for in-body correcting the XCD28P color cast. I am waiting for the answer, but I will postpone the purchase of the XCD28P for the time being.
