Otter ContactForm-Form options and submit messages are used for all translations

Hello,

On my website I’m using a contact form. My page has 5 translations created and each use this form. I’m able to change fields on each of translated page to show different labels, but changing form options like Email To/Email Subject and Submit Messages (Success Message/Error Message) affects all translations. Basically I can’t have different success and error messages for different languages.

Is it achievable somehow? If not I think it is a good candidate for feature request.
