Dynamic copy function

I am setting up a component that copies itself in the Y. Is there a way to also copy it in the X at the same time? Small vertical stub circled in Red on screenshot:

Copies are linear (n-copies), and you need to map the PosX and the PosY of each copy in a row x column array.
Look for the ‘Tile Grid’ example in the component panel,
‘Dynamic Components training’ folder.
