How to List Co-Op on Resume?

So, this might not be the best place to post this. However, I’m having trouble finding much of anything useful when I google it, and figure that you guys are pretty knowledgeable.

Essentially, my question boils down to this: Should you separate co-op rotations on a resume when they were for the same company, but you worked in a different department each time? For example, my first rotation was with the supplier relations group, and the next was with the product industrialization team. They were all done in a row with no other work experience in-between, so the whole reverse-chronological order thing doesn’t really help.

If I can help it, I’d like to not have to write out " XXX company, Y location" multiple times for the sake of space savings.

Thanks.

I would separate them. At the very least, make it clear that each rotation had different responsibilities, departments, and achievements.

I would keep them together but make it clear what responsibilities go with which rotation.

Not a co-op, but I’ve interned twice at the same place in very different programs, and my employment section on my resume looks like this:
