[Plugin: FeedWordPress] Syndicate only some posts from feed

Hello,
there are two questions about this great plugin:

1) When I insert some feed into this plugin and I want to publish only selected items. I can set to prepare only drafts from this feed and then I can publish some posts and delete others. But when FeedWordpress starts its work again, deleted posts are redownloaded once again. Is there any datetime hook to tell this plugin “Download only items which are new since your last download?” Or is there any other solution?

2) When RSS feed contains only title, is it possible to parse from this URI (post title) for example first sentence directly from website?

Thank you for your help…
