same category product display block

Hello Everyone,

I would like to add a block to each product page which displays, let’s say “related products”, literally random products from the same category. I couldnt find a way for such a block the only thing close to what I am thinking is placing the related products one by one manually (from filling options) which would be simply impossible!

Do anyone have any recommendations?

Thank you in advance!

I also would like an answer to this.
