Yahoo switched all of my groups to fully-featured display format. How can I undo all of them at once?

Question

This appears to have been a unilateral, arbitrary, and unsought act on Yahoo's part, and I'm happy with the "traditional" display format -- it doesn't jumble up the formatting when I hit "reply". But I haven't a way to switch all my groups back to "traditional" without going to each one individually and re-setting it, which is just plain tedious. So I'd like to undo the whole mess at once. Any ideas? Thanks!

if the whole group was reset to that, I'd let each member change their own. there is no way anyway to change it back all at once, sorry
