Option to change from 'Scaler' to 'Duration'

It would be extremely nice to change a habit’s unit without creating a new one. e.g: from `Energy` to `Mass` or `Scaler` etc. (For me) This is mainly for habits that I wish to keep but change the way I approach it, for e.g sometimes I don’t want or need to study for as long as I put on my habit but still want to complete it and mark as done because it’s enough for that day.

As of now I’d have to delete my habit and create a new one to do that.

Would this be possible? If so, please implement this feature.
