Target for Source

In settings there’s a ‘Source link open behaviour’ and that gets applied to the feed item that gets pulled from the source; in my case it’s set to new window. However, I do not see the option to add the same behavior to the source link itself, the site where the feed is pulling.

It would be really useful to be able to open the source itself in a new window so people are not leaving my site to visit another.
