432111 Magento Multi-Site And Google Merchant Center Integration

we have a Magento multi site setup, let's call them [login to view URL], [login to view URL] and [login to view URL] (There is a total of 7 domains like this) the main site is [login to view URL] (this is where magento is installed) with [login to view URL] and [login to view URL] being subsites with feeding from the same database as on [login to view URL] (different product pricing in currency of the local country and in some cases different descriptions for each domain) The Requirements for this project are: 1) we need Google Merchant Center integration for each site, for each site we need that specific site's products and prices and all attributes mapped to google merchant center (each site may have different model numbers and different prices for each country, this is all stored in magento under each product) 2) create a google sitemap for each site and have it stored in the site it was generated for so that google can automatically pick it up for example right now if we generate a site map (let's call it [login to view URL]) for [login to view URL], it is stored by magento in [login to view URL], we need it saving in [login to view URL] this has to be done for 6 sites (the main site google sitemaps are working properly)
