How to display item description instead of content

[mcnesium]

Many feeds provide a description for each item besides the actual content:

<item>
    <title>Example entry</title>
    <description>Here is some text containing an interesting description.</description>
    <link>http://www.example.com/blog/post/1</link>
    <guid isPermaLink="false">7bd204c6-1655-4c27-aeee-53f933c5395f</guid>
    <pubDate>Sun, 06 Sep 2009 16:20:00 +0000</pubDate>
    <content:encoded><![CDATA[…]]></content:encoded>
</item>

Is there an option to display the description instead of the full content somewhere, that I have missed? If not, how could we achieve this? Would this be a setting in config.ini or rather a separate RSS-Feed type spout?

This might be another use case for the spout transformers.
