RSS, how to import more at one time

hi, I’m migrating to wordpress and it’s simply great!
just a question: may I import and mix more rss feeds at same time?
for example, instead of having:

title of the feed 1
item1-feed1
item2-feed1

title of the feed 2
item1-feed2
item2-feed2

I would like:

title of feed 1 and 2
item1-feed1
item1-feed2
item2-feed1
item2-feed2

(or may be shown by date, newest up)

may be there’s some plugin already done or some little hack possible?
thank you in advance for your time,
diego
