How to change URLs in Prestashop?

Question

Prestashop

All welcome. Those who previously worked with this engine know that categories and products have id in links. You can remove this with the Clean urls module, which is actually done. But there is one more task, to set a slash at the end of the product link, now like this: category / subcategory / product-name. It is required to do this: category / subcategory / product-name /. Does anyone have any thoughts? As soon as I did not try to edit the Dispatcher, 404 constantly pops up. I would be very grateful for any thoughts and help.
