[NX 9] Adding windage, fixing warped part?

[who8myrice123]

Hey guys, I'm new with fixing warped parts and adding windage.

I've been given a part and the coordinates for each point on the top surface that deviated from the original model.
All deviations/warpage is in the Z-axis.
The previous designer has already added as many ribs as they can to support the part (not shown in image), so additional ribs isn't an option here.
How would I go about fixing these points? What tools/features (x-form, global shaping?) should I use in NX to compensate for the deviations?

Pt 1:
XYZ = (1826.285, 629.228, 850.983)
Mean deviation = 1.639

Pt 2:
XYZ = (1806.696, 631.526, 848.632)
Mean deviation = 1.195

Pt 3:
XYZ = (1807.640, 617.653, 848.342)
Mean deviation = 1.106

Pt 4:
XYZ = (1825.641, 618.767, 850.597)
Mean deviation = 1.615

Any help would be greatly appreciated!

You could try "Global Deformation" using "Points from File" as the Defined By

Text document example would be like:
-334.612 495.821 -109.404 0.442 2.184 8.060
-333.567 495.182 -109.236 0.441 2.169 8.019
-334.621 494.557 -109.067 0.438 2.186 8.072

Format: actual locations in X Y Z followed by deviation in X Y Z
