That would be better solved with a contour train. Here you can then enter the exact route to be traveled and adjust the feeds at the respective points using a technology parameter. You can also create something like this as a component.
The horizontal pocket is simply knitted.
I found a way do it, if you replace Horizontal Pocket with Pocket with A-Angle, you can machine the same feature but also define the Z Feed Adjustment. Very strange that the features of each Macro are so inconsistent across the software, there are many examples of similar inconsistencies.
Using contours would be a good alternative but pockets are pretty flexible as components
