Limit narchive to show only one year as default?

Is it possible to have the narchive file show only the most recent year as default? If so, how would I do that? Narchive is nice and simple; I was just hoping I could make the default show less so it won’t take ages loading all of my past entries.

Here is a copy of an original narchive file:

Thanks!
