Changing The SEO Rich Snippets plugin

My site is [login to view URL] The site is on Hebrew wordpress 3.6, using the theme Twenty Twelve and 19 active plugins I have the The SEO Rich Snippets plugin currently installed [login to view URL] This plugin adds Rich Snippets for review website and allows to configure snippets from the dashboard.. The snippet can be checked with Rich Snippets Testing Tool [login to view URL] The want to have the plugin changed: Currently the review rich snippet configured in the dashboard appears on every url of the site. I want the reach snippet to continue to appear in every url on the site with one exception - they should not appear on single posts. For example [login to view URL] Work should be done in 24 hours after being awarded the project. Freelancer should send me an amended version version of the plugin that does what I want. Freelancer will not have access to the site. Freelancer should allow 7 days for testing after he finishes his work, before getting paid.
