I'm using following code to route urls to specific template
'<restaurantSlug:{slug}>-nutrition' => ['template' => '_nutrition/restaurant'],
is there a way to limit slug results to specific channel otherwise I can add anything before -nutrition and it's getting routed as well. Which is not that clean and also don't allow me to use redirects (retour plugin) since the page don't actually throw 404 error.
Or any other approach that I've missed?
Thanks.
