Using 'MB Favorite posts' plugin for two purposes

We'd like to have two buttons on our posts: 'Favorite this post' and 'Save this post to read later'. Technically, either of these could be run by this plugin's functionality. But is there a way to have both at the same time by using this plugin?

For example, is there a way to duplicate the functionality of this plugin so we can have two types of uses for it?

Or, is there a way to categorize favorites so we can perhaps split them up that way?

Thanks
