How to cancel local port forward from ssh console

Question

I can forward local ports using the command below

ssh> help
Commands:
      -L[bind_address:]port:host:hostport    Request local forward
      -R[bind_address:]port:host:hostport    Request remote forward
      -KR[bind_address:]port                 Cancel remote forward

ssh> -L 8080:localhost:8080
Forwarding port.

But how to cancel that port forward? I see the -KR for cancel remote forwards but there does not appear to be a -KL to cancel my local forward.

Asking for another forward on the same port (hoping to override the old one) gives this message

ssh> -L 8080:localhost:8081
bind: Address already in use
channel_setup_fwd_listener: cannot listen to port: 10101

There seems to be no way other than to exit the connection and start over. I'd love to be proven wrong...
