Similar products, only from a child category?

Question

WordPress

Hi Toaster!
Such a task:
to make it so that in Woocommerce on the page of a single product in the element "Similar products" only products from one child category with the current product are displayed, and not from all general categories and tags.
For example:
"Sale\Beds\With lifting mechanism" - only products of the category " With lifting mechanism " and only from the main category "Sale/Beds"
" Sale\Beds\Transformer base " - only products of the " Transformer base " category and only from the main category "Sale/Beds" ???
Now all beds are shown in a row.
PSquestion, but still does not want to show how to.
If there are few products in the subcategory, then it seems to display them as needed, but if there are a lot, then it starts to catch for some reason from similar categories ...
maybe someone came across, maybe using functions.php, just what to write)) ?

You do not need to write it here, but on the official website of the VP, such as a bug, etc. OR just ask in the comments to the plugin, maybe someone heard something.
