Creating Grid with adjustable column widths

Trying to create a tile facade for a large building with a grid profile, and I want every 4th column to be less wide then the rest. Does anyone know how I can create this? Ive attatched an image of what the rid looks like

Welcome,

You can for instance construct the grid manually like this:

Hi @Cooper_Wegener

Here is my solution.

First panel list values are x-size, second is y-size and then how often you want it to repeat, similar inputs like the grid node. The split tree at last is only to select specific cell.
