Using links as the source for fetch_feed

I am trying to display feeds from a couple of my blogs using the build in function fetch_feed() however I stumbled across a few problems.

I am storing the rss urls in the links section and will be calling the link_rss as the input for fetch_feed(). I know that I would have to deal with an array, perhaps nested arrays??

Can someone be kind enough to give me a way of pulling all the link_rss fields into one single variable which can be use for fetch_feed()??

Having the variable in the form of an array would be great so I can just plug it in to the function like so fetch_feed($variable).

Any help would be greatly appreciated. Thanks!!
