New Posts - sorting first by forum then by date

[crepo]

After moving from Snitz to vBulletin we have a lot of questions by or visitors for one option.

If we use "active postings" (same result like New Posts) on Snitz the postings are sorted by forum and then on the time of last post.

In vBulletin al the new posts are sorted by time.

Is there a way that we can use to change the "New Post" that it first sorted the forum and then the time?

Thanks,
Peter
