Procedural material - can you rotate a pattern?

Hi,
I downloaded some procedural materials to use for creating tile materials, from here: https://forums.unrealengine.com/unreal-engine/announcements-and-releases/asset-sharing/108821-creating-semi-procedural-materials-livestream?136096=

They use a function called Plank_and_tile and I made the exact pattern I want but I can’t, for the life of me, figure out how to rotate it by 90 degrees. The material uses a “shift” option to generate the tile pattern but it only works on the X axis, I can’t shift my pattern on the Y axis.
The function looks like this:

My material looks like this, I just need to rotate it by 90 degrees so that the tiles shift on the Y axis:

I tried using the CustomRotator but I don’t know where to plug it in. I am new at UE4 and I’m trying to see if I can use it for architecture visualizations.

Any help would be greatly appreciated.

Why exactly can’t you just rotate the UVs?

You need to look for the TexCord node in the material. There will be one somewhere off to the left, Add nodes like the picture below and wire where the TextCord used to go into the custom rotator out. So you just sneaking that extra custom rotate node in between the texCord and wherever it goes off too.
