Could pagenavi-css.css be limited to only on needed pages?

I know there is an option to disable the CSS but I'd prefer to use it, however for most projects I only need PageNavi on a few templates. Would it be possible to have wp-pagenavi dynamically enqueue the stylesheet only when wp_pagenavi() is called?

I'm just trying to squeeze every drop of optimization for my projects, and before I do any manual overrides I thought I'd ask.

Unlikely I will add it in, but feel free to send in a PR if you did it =)
