Guys,

I have a big problem, and I do not know how to solve it.
Maybe a plugin is needed, I do not know.

On my website have 10 “Pages” with products I produce, let say:
http://www.site.com/wheels
…
wwww.site.com/shoes

My site will be mostly static, and only contents new would be my production achievements I do for my customers. will post them as “Posts”.
Those posts can land in:

http://www.site.com/achievements/wheels/post123.html
http://www.site.com/achievements/shoes/post124.html

And I do not want it.
It will lead to keyword cannibalization.
And it can finally end, that google will position higher my /achievements/wheels, than /wheels. What will be very wrong.

I want to set folder /achievements for each my Page.

So I want them to land in my Pages like this:
http://www.site.com/wheels/achievements/post123.html
http://www.site.com/schoes/achievements/post124.html

And I can not find solution for it, becasue categories are different for Pages and Posts.

How to do it?
