You can. See my post here:
https://bitcointalk.org/index.php?topic=5112334.msg49854683#msg49854683For example, this link -
https://bitcointalk.org/index.php?action=recent;boards=1,74,77,86,6,37,98,100,138,97,231,261,14,40,41,42,76,137,81,4,12;patrol - will show you all recent newbie posts from the boards in the "Bitcoin" section only.
You can also use this link to see newbie posts from all boards, but with bounty posts excluded:
https://bitcointalk.org/index.php?action=recent;patrol;nobountyAh perfect. I thought I remembered vaguely doing it before, but I assumed I just ignored a few sections, but didn't bother testing it recently. That'll be perfect for moderation as well as meriting new users.
