Placement rules: language?

Hi!
I have a multi language site, and I was wondering if there was a way to associate custom field groups with the languages used in the site
(for example, create a field group that was available only for a specific language).

I’m using WPML plugin, which generates different pages for every language. So currently I am doing this by listing the pages one by one in the ‘Posts’ Placement rules field.

If there is no easier way to accomplish this, would you consider this functionality for future releases?

Thanks!
