SlimerJS ignore SSL errors

I'm pretty far down the path of incorporating SlimerJS into my web scrapers and I've come across an issue. One site I am working on just had their SSL certificate go invalid. Upon looking at Slimer's SSL documentation, it appears that they do not support PhantomJS's ignore-ssl-errors option. Is there a way around this? The SSL certificate error page that appears in the browser does not have any sort of continue button that I can make Slimer click. As an FYI, I am using CasperJS as a wrapper for SlimerJS.
