How to bring clones to Unity (Instansing, clones workflow question)

Hello everyone,

I've made a wine shelf in Cinema 4d, using one bottle model and cloner object. I want to bring this thing to Unity, and know I'm stuck at how to do it. I don't want to bring this shelf as separate objects because a lot of memory will be used for dozens of bottles, and I don't want to bring this object as one solid piece of geometry because it would loose details in texture (as soon as it will become one 2k texture instead of many). So, I'm stuck here trying to bring this thing, in the same manner, it's working in Cinema 4d, where it's all clones (instances) of one object. I know that I can bring one object and use it as a reference object, but if I do so, I would need to place all reference objects by hand (manually), what I don't want to do either. So I will be very appreciated for some advice, thanks!
