How do I import multiple RSS feeds to my site, but edit and post only spesific post`s

I would like create a rss feed in my site where i import feeds to my back office.
After getting them, i want to choose the ones i want to post (with a check box or in a similar way), and edit them so they all look uniform on my site (same font for title, same font for body etc).
Do you know any way i can do that ?
