product in same category

hi

would it be possible navigate through products only in same parent category…?

an example of what I want to get:

I have two categories named “parent cat 1” and “parent cat 2”. “parent cat 1” has two subcategories: “child cat 1” and “child cat 2”. the “child cat 1” has one “product 1” and the “child cat 2” has one “product 2”.
“parent cat 2” has only one “product 3”

the tree would be:

parent cat 1
    child cat 1 > product 1
    child cat 2 > product 2

parent cat 2 > product 3

by default, in the single product page, there are next and prev buttons, and you can navigate through all product.

I would want that when I’m in “product 1” (which belongs to “parent cat 1”) only could navigate to “product 2” (which also belongs to “parent cat 1”), but no to “product 3”.

can it be possible…?

many thanks
