Lunch Box Space truss for Organic Surface UV direction Adjustment

Hi Guys, I am currently working on an organic space frame using the lunchbox plugin. However, I am facing some problem that the U-V direction division is not my desired outcome (see A1 and A2 direction in the screenshot), what I want is that the surface divides using the B1 and B2 direction, so that it aligns with the roof shape surface.

May I ask is there any way to fix this issue? Thank you very much!

Finding ways to divided this without UV is key to gaining control over the panels.

There is a plugin called ShapeMap that may help: Equal panel size - #6 by jessesn

And then there is Paneling tools to work across one or many surfaces: Equal Grid Across Surfaces - #10 by scottd
