How can I configure Vi mode in GHCi?

I just learned about Vi mode in GHCi. I already added editMode: Vi to my ~/.haskeline file. There are two tasks that I wish to accomplish.

1. I would like to remap my escape key to jj.

2. I would like to configure GHCi to show me what mode I am in similar to how I can add set show-mode-in-prompt on to my ~/.inputrc file for readline.

I have read through some of the haskeline documentation but have not been able to find an answer.
