I think you can specify the in-group sort, and specify a very small number (perhaps even one) to go in each group. But you'd have to store the length of each body and sort by that.
I'm pretty sure grouping is trunk-only. The problem here is getting something that applies just within the group and not across groups... I'm not sure how to tackle that other than perhaps the grouping idea... Best Erick On Thu, Apr 7, 2011 at 6:36 PM, Peter Spam <ps...@mac.com> wrote: > Would grouping solve this?
