Alternate Wall Directions does not apply User Specified Z Seam Alignment correctly

[philippeholthuizen]

Is your feature request related to a problem?

I need to print a hollow double-walled volume from flexible filament, where the 2 flanges need to connect seamlessly higher up in the print. However, because of the consistent travel direction of the hotend, and using flexible filament, the edges of the flanges are being pushed out of position. And I also need the seam to be in a specific position.

Selecting Alternate Wall Directions would potentially solve that problem, as the stresses on the flange are equalized. But that option seems to lose the seam position on the alternating layers. Is this something that can be fixed in future Cura versions?

Using Cura 5.7.1.
