Hi Yellow, Thank you very much for the help.

--> this is fine, if everyone wants it, we can do it
If category is deep, it's not good for seo is it? so i am satisfied with what we currently have which shows only one category.

I ask you for people who want sub category link to be like this:
car-1/honda-2/civic-3/, is it possible to choose and decide above 2 choices from admin?

Which means SSU may not be able to support as many as it can now. Now we run into the same problem Magic Seo faces.
I think to remove those special characters is good idea, if i can remove special characters, link address will be more tidy.
but i don't know how difficult it is to remove those, and you said SSU may not be able to support as many as it can now,

that's bad news... i prefer SSU support rather than removing special characters.
