You might want to ask the author of the pack (which is not me) directly. He’s in the best position to help you and make your request come true.
Edit:
I took a look at the node setup and I managed to solve the problem and add the feature request.
Everything happens in the Br’cks_v1.002 node group. The problem was caused by a single math node, I put it in a frame called “Annoying node” and muted it. What it did was randomly splitting bricks. In real life, a proper wall has bricks of the same size unless you only have broken bricks which is not ideal.
The feature request is achieved by a group of nodes put in a frame called “Brooklyn effect”. This group of nodes is controlled by a parameter called “Headers every n rows”. Any value lower than 1 will disable the effect, otherwise the effect will be shown with the number you specified.
Here is an example with different values and the blend file:
