Grrr... Gmail...

Okay, so the conversation sorting feature of Gmail is pretty cool, and for normal stuff I like it. But sometimes it sorts notifications (like from LJ or in this case hold notices from the library) in stupid ways. I just realized that my hold on "The Hunger Games" finally came up... four days ago and then expired yesterday. I didn't see it before because it was erroneously grouped with another hold that came available that same day. Grrr. Now I'm back to hold number 47 out of 47 on the waiting list.

Anyone know if it is possible to turn this feature off for certain senders?
