Importing multiple forms on plugin activation

I'm currently importing a single form upon my plugin's activation. Here is the code:

define("GF_IMPORT_FILE", plugins_url( 'templates/get-a-free-estimate.xml' , __FILE__ ));
function nwtd_lpfs_import_form() {
	if(defined("GF_IMPORT_FILE") && !get_option("gf_imported_file")){
        GFExport::import_file(GF_IMPORT_FILE);
        update_option("gf_imported_file", true);
    }
}
add_action('init', 'nwtd_lpfs_import_form' );

Is it possible to import multiple forms using the above code? I'm not exactly sure how i'd go about it.

TIA
