Is there a way to import RSS feeds into a post/page instead of the sidebar?

Try this… I haven’t though:
https://www.underjc.com/2007/10/firstrss-plugin-for-wordpress.html

Or this one:
https://www.ads-software.com/extend/plugins/parteibuch-aggregator/

Thanks, othellobloke.
I have problem using parteibuch-aggregator (the config screen does not show up) but firstrss works beautiful.
However, Firstrss only supports one RSS feeds, and if I want to post multiple RSS feeds into one post/page, do you have any suggestion what I need to do?
Thanks in advance.

Try https://www.pheed.me their widgets work perfectly for that sort of thing.

you can also aggregate all your rss’s into friendfeed.com;)
