Prusa Slicer 2.9.0-alpha1 - Center Scarf Seam length on rear placed seams

[jbnarch25]

Issue
Rear seams have recently been revised to place the seam in the center of an object as it worked in version 2.4 and below. The new Scarf Seam feature however doesn't center the scarf length on the seam location and is offset to one side.

Slight workaround
Enabling the printer setting to "Prefer clockwise movement" helps keep them aligned to the same side of the seam but the offset still creates an asymmetry that might affect the design of an otherwise symmetrical part.

New Feature Request
Please consider having the default Scarf Seam behavior for parts with rear seems to center the scarf seam length. Alternatively an option to enable centering in print settings as well as in per part settings overrides would be fantastic.
