Smaller Instant Pot....pot?

I had another brand of pressure cooker, and my husband bought me an instant pot for Xmas. I love it, but it's just the 2 of us, and the pot is kinda huge. Pretty sure it's the 8 qt.

Is there a smaller pot I can get to put inside the big pot? Or could I use a regular metal bowl inside the regular pot?

ETA: pot-in-pot was the term I was looking for! I knew what it was, I just could not think of it this morning for some reason. 😂 Thank you!
