Overwrite posts

Hi There!

First of all, thank you for your great work at your great versatile plugin!
recently i am working on a site, using your plugin. It transfers posts from 3 different url’s. Afterwards extra content is edited in the generated posts. After the stream is synchronized again, the edits are all overwritten by the content of the rss feed again.

I think previously this was not the case. How to prevent edited posts to be overwritten by the rss feed content?

Thank you! Ari?n
