Changing url: Remove post type in the url

Hello, thanks for this plugin.

I would like to remove the custom post type in the url of pages.
Example:

https://example.ch/service/graphisme/print/logo-et-identite-visuelle/

Would be:

https://example.ch/graphisme/print/logo-et-identite-visuelle/

I tried editing filters in filter.php, but if i define empty post type, the plugin overwrite with the post type.

Thanks
