Hi Phil.
As you notice most of the Cladding presets are based on the Macros so you will probably need to edit current Macro.
For Rotation, you can try to change Auto Align to `Spline`.
If you need more control then leave Auto Align to `X -->XY` and introduce a new numeric node for Z rotation angle and connect instead Horizontal/Vertical node.
To preserve the Horizontal/Vertical parameter you can just add Arithmetic node and set it to ADD, like in pic.4.
After editing macro return to Top Level and you should see a new parameter for Z rotation.
I hope this will help you.
Best regards.
