"Also in this Category" Product Block

Do you know if it’s possible to have a random “Also in this category” products block to show in the Product page?

We have Random, Also bought, Best sellers, etc… But not this feature.

How hard is it to code this?

I think it is very simple, just add a block with manual products and fill it with category products. You have to do it manually but if you really want this feature, you can do it!

The only thing is that I have 200+ products

That is the only way I can think about it!
