Is there a type of file that remembers the different components of your design (2D)?

I used the app Assembly on iPad. I was wondering if there was a type of file that would distinguish between a square used for the body and a circle used for the eye, such that I could rotate the eye (or do more with it) without influencing the body.

Thank you,

Not sure if I fully understand the question but, if you want to translate and rotate graphic elements separately, you simply create them as separate gameobjects.
