Populating a tiledlayout vertically rather than horizontally

Hi, I have an 1D array of images in a cell array.
I want to montage them using my own settings, so I have been using tiledlayout.
I must have 3 rows, and my total number of images is always a multiple of 3.
n=app.ImCount.Value; % number of images in my cell array
tcl = tiledlayout(3,ceil(n/3),'TileSpacing','none','Padding','compact'); %tight
for i=1:n
IM=app.imgArray{i};
ROI=imcrop(IM,rect);
ax=nexttile(tcl);
myImagesc(app,ax,ROI); axis(ax,'image');
end
Say I have 12 images, rather than have the layout like this:
1 2 3 4
5 6 7 8
9 10 11 12
I want this, i.e. populating vertically
1 4 7 10
2 5 8 11
3 6 9 12
I thought there might have been an option in the tied layout but there is only a complete "vertical" arrangement possible.
So my idea next is to just index the images like 1,4,7,10,2,5,8,11 etc, but have no idea how to do this or whether this is a good way anyway
Thanks

One option could be to use the TileIndexing property, and set it to 'columnmajor'.
