Placing multiple custom models in the same position without changing/replacing model

Is it possible in MCreator to make it so that I can place different custom models in the same position (16x16x16 block area) without having to make a separate model containing the items I want in the same block position each time I want to place an item?

So to simplify it, I'm gonna try to give an example;

I have two custom models, both of them are squares the size of 8x8x8 pixels. I want to place both models in the same position (meaning in a 16x16x16 pixel block area).

Is there a way for me to place those two separate models in the same block position but next to each other without having to make another custom model containing those two models?

I know it might be a bit confusing to understand, so if anyone is willing to help, I can answer any additional questions if it can help to clarify this.

Thanks!
