Does the Slide in Plugin accept a gravity form

In my site I am using the slide in plugin http://acrirlty.com/psp/ with the mailchimp api integration and it is working perfectly. I would like to use the plugin with a gravity form. I entered the form in the editor section of the plugin and only the [gravityform shortcode] text appears. Is there a way to add the ability to use shortcodes with this excellent plugin? Is it something i can add to the themes function php? add_filter( 'slider_plugin', 'do_shortcode' );
Thank you!
