Compatibility with Polylang

Hi,
I’m using this plugin, it’s fantastic!

is it possible to update it to have multiple text/url/button text for multilingual websites?
I have a french and english version of my website, and I need to have per domain a different message, a different call to action text and different url?
The only “dirty” hack I found so far is to change “notification-bar.php”

and use something like this for instance to display the right message:
<?php pll_e('message'); ?>

Is there a way to “override” these fields so I don’t touch the plugin core?

thanks!
