Share RSS on Facebook and Groups Pages

Share RSS on Facebook and Groups Pages I need a script that can share RSS on Facebook pages and Facebook groups. the script has to share the rss items on facebook page and groups. Ira share X numbers of items in a single post and a personalized message for each RSS I need to choose the amount of items that will be shared. Choose the time each rss will share on facebook .. I want the rss to share with facebook pages and groups at the same time. I need in the RSS configuration that I can choose which page or group will go that rss. Example [login to view URL] will share to page 1, page 2, group 1, group 2 I am certain that they offer the correct value because and what I will consider, nothing to increase after the value. Nescessary time should be the correct time for this. If I put 3 days I need it to be completed in 3 days.
