How to manually create chunks and is it worth?

Hi I wanted to ask how can I manually create chunks or shared components for multiple otherwise different entities and if it would increase iteration speed/performance?

I literally answered my own question and I realised that minutes after posting this. Consider it resolved.

Well nice to know you solved the problem.
But it, would be worth to post the solution, for future readers as well.

Well It was more of a theory question and the answer (at least I hope so) is using shared components.
