Spring cloud stream 4 Polled Consumers issue with changing the binding name

Question

I'm using spring-cloud-steam version 4.0.1 to implement Polled Consumers. I pass the arg --spring.cloud.stream.pollable-source=myDestination. This creates a channel myDestination-in-0. However I want to rename the channel to input. So I tried passing arg spring.cloud.stream.function.bindings.myDestination-in-0=input but it does not work. It still create channel myDestination-in-0. How can I rename the channel?
