Does Nuna car seat click into stroller?

I'm curious to know, does the Nuna car seat seamlessly click into the corresponding stroller model? It would be incredibly convenient if it did, allowing for a smooth transition from car to stroller without any hassle. Is this functionality standard across all Nuna car seats and strollers, or are there specific models that are compatible with each other? Additionally, is there a specific locking mechanism or indicator that lets you know the car seat is securely attached to the stroller?
