Thanks to Alex Munoz, Google and dcshooter who kindly supplied to link to Alex's very useful approach to customising colour profiles for the 645Z for use with Capture One Pro.
Following Alex Munoz's website, I have just used the Advanced Color Editor function in C1 Pro 8.3, to produce a camera profile: a C1 Pro ICC file (.icc or in fact .icm where 'm' denotes a manual edit of an existing icc file).
Alex describes the process here

I started with the 645Z colour profile that was available from Alex's website. This was a slight improvement on previous customised ICC files I had created using a similar process.
I attach Dropbox links to my 645D colour profile if anyone wants to give it a try, and for the WB and X-Rite ColorMatrix test shots, the latter being used in constructing the 645D colour profile, as per Alex's video.
#1 My customised P645D ICC (.icm) file:

#2 The X-Rite ColorChecker test shot DNG file:

#3 The WB DNG file I used to first set the WB in #2 (I had selected Cloudy WB in-camera when photographed):

I don't regard this colour profile as 100% by any means, but it is a visible improvement on my previous attempts and I'm finally coming to the conclusion that I will be able to continue to use C1 Pro as my preferred RAW editor. (Phase One's attitude to the P645D / Z stinks, however commercially predictable).

Not sure how to automatically assign the 645 icc profile when each image appears on C1 viewer but only a second to apply it manually...
@snapper99 - Go to the 'Base Characteristics' tab. look for the ellipsis (...) sub-menu. Select the menu option 'Save as defaults for DNG file' and this will save the currently selected ICC Profile as the new default. Of course that ICC profile is probably the one the user has just produced via the above method!
