SSH Tunnel - Dynamic Outgoing Tunnel

Hello! When creating an SSH Tunnel in the iOS client in the Outgoing Tunnel Settings, if I select "Dynamic", set a local address of 127.0.0.1 and local port, I believe the Destination should be automatically set by whatever host I'm attempting to connect to.
Currently, if I select Dynamic and add a local address / port I receive an error message "The destination cannot be empty", but there is not field available for Destination.
This seems like a bug - I don't think a Destination should be required for the Dynamic setting, and even if one is required there is no field to put it in.
Thanks for your help!
