Product design generation

I was trying firefly for my first time today, and I was generating car designs. After a couple of minutes trying this AI, I found that it is hard for Firefly to mantain simety when generating these, so I thought that maybe it could integrate something to learn when to be simetric (we found simetry in almost everything in nature) and when not, so that the generator can be more appropiate to the prompts! That´s everything, hope this helps!
