Woocommerce permalinks,

Hi all.
I would need some help with woocommerce permalinks.
In woocommerce permalinks what ever my setting is, it seems that the title of the product comes as a %post_name% in the end, even though I didn’t put in %post_name% in the end.
Now this might be a good thing if you have a sight written in alphabet, though I have a Japanese sight and Japanese sucks for links and other things. I would like to end it with for ex %post_id% but when I make the settings /products-page/%post_id% the permalink doesn’t end with the post id but ends with the title name. And if I try to manually change it, while doing product it isn’t possible.

Is there any way to change this?
