Applying Curtain wall grid to irregular wall surface

Would greatly appreciate any advice on applying a curtain wall grid to fit over this irregular wall surface.

When I try using Panel.PanelQuad node or Lunchbox Quad Grid by Face node, they just generate regular rectangular grids to the overall rectangle, ignoring the “L” shaped profile or openings. I hope to project a 48" x 48" panel grid over the “L” shaped wall while keeping its 5 irregular openings uninterrupted.
Thanks for any guidance you can provide.
