I have a RSS link that combines multiple categories using the markup below. It works fine.
<a href="http://DomainName.com/wp-rss2.php?cat=1,2,3,4,5" title="RSS Feed for all posts in MyCustomName"><img src="http://DomainName.com/images/icon_rss.gif" alt="Feed for all posts in MyCustomName" /> MyCustomName</a>
But when viewed in a RSS Reader, this displays the feed title of "SiteName >> FirstCategory". Naturally, with multiple categories within this feed, I don't want the title to use the first category (besides, that's the feed title for the *real* first category's feed).
Is there a parameter or method that would allow me to use a custom title in multiple category feeds like this? Thank you.
