How to

#1. First you need to set Grid – Simple (or Grid – Overlay) to 4 columns

div#gridThumbs {
    grid-template-columns: repeat(4,minmax(0,1fr));
    grid-template-rows: repeat(36,minmax(0,0.2fr)) !important;
}
.portfolio-grid-overlay .grid-item {
    padding-bottom: 0 !important;
    height: 100%;
}
.portfolio-grid-overlay .grid-item .grid-image {
    position: static;
}
a.grid-item:nth-child(5n+1)  {
    grid-column: ~"1 / 3" !important;       
} 
a.grid-item:nth-child(5n+2)  {
    grid-column: ~"3 / 5" !important;
