Join breps for a regular facade in Grasshopper

as a complete beginner, I am now dependent on your help.
I would like to put a vertical facade on my freeform, created in Rhino, in Grasshopper. So far so good, unfortunately the divide surface works for each deconstruct brep separately, which makes the pattern of the facade very irregular. Is there any way to combine the individual breps into a single surface and apply the divide to the entire outer skin?
Maybe there is also a completely different solution, feel free to let me know!

Thanks in advance for your help! (9.5 KB)
