Add extra parameter to the config.toml menu

Hi there! I need to create an extra parameter for each menu item, I know the existence of pre, post, identifier, etc… but for some reasons I had to occupy all those parameters … the extra parameter that I need is really to put an " data-qa=‘XXX’ " in each menu item… “Using the {{ .title }} or {{ .name }} would be a great idea if the web were not multi-language”…

I’m stuck in this, any help will be very useful, thank you very much everyone!!!
