Getting Envelopes to Follow Project Tempo Change?

I have a project that is aligned to a tempo that is double what I want it to be now. Is there a way to change the tempo and have the automation envelopes align with the new tempo, as the audio clips do?
 
Or in other words... I pulled all audio clips start times to the beginning of the time line before I changed the tempo... so all audio clips are properly aligned to the new half tempo. However, the automation envelopes are now twice as long as they should be. Is there a way to get the automation envelopes of the tracks and buses to follow the audio clips' change properly?
 
Thanks.
