Custom SEO-friendly URLs in OpenCart and custom it

I know OpenCart provides SEO URLs for products, categories, manufacturers and information pages, but it doesn't look like there is anything built-in (at least prior to version 1.5.0) for anything else. - Install OpenCart 1.5.0 - Custom [login to view URL] link : (link custome here [login to view URL]) + If if one category don't subcategory: first page title,store,the product store name | product, store name | categoriy + If if one category has subcategory: store name | sub category name (not show like store name | category | subcategory) Thanks Vick Nguyen
