That's a rssfeed datatype. On several of my web sites, I have a directory of sites (type links) and if they have a rss feed, I import the items under them.
Doing that with the current interface is a real pain :
1) create the link,
2) go to rss,
3) create a new rss import with the same name than the link you just created
4) change the type of the content class for the items (no way I want to create folders, as offered by default)
5) set the right attributes,
6) browse the destination node to pick up the link you just created
7) find again the url of the rss you had on your clipboard at 1), but since you had too many manipulations in the meantime, you lost it 8) Save
When they want to add more than two, they usually have a nervous break down (or want to kill me).
With the new rssfeed datatype added on the link class, you just put the rss address at the same time than you create the link and that's it, it creates the import in the background.
