Woocommerce front-end

I want to know if it's possible to let my user add a file from the frontend, for a woocommerce product. I've seen that wp file download is compatible with woocommerce but I don't want my user to access my wp-admin dashboard ( it's a multi vendor website ).

Is there any meta key that I can map in my form with the media file ( I use crocoblock jet engine forms ) or do you provide a form to let submit file product from the front end?
