Duplicated key bindings

Hey, I'm a tmux user, and what I do in tmux I configure two keybindings for the same action, for example:

bind -r n next-window
bind -r ^N next-window

This allows for a more flexible behavior regarding the ctrl modifier. After pressing ctrl+<leader> I can keep ctrl pressed for a rolling motion as I move to the n key. Or I can release it which is the default behavior.

But herdr doesn't seem to allow duplicating keybindings like this. Do you know any workaround?
