Repeating small parts in CC

I’m making small right triangles for some gluing guides (X-3.5in X Y-3.5in) and nesting them on a 24x24 sheet of 1/2in ply. Is there any way to copy and paste one and just repeat in CC or do I have to draw and do the toolpath for each one?

Ctrl c will dupe a selection, but not the associated toolpath.
