I agree. This is huge for me and is something all other major DAWs do. Copying automation from one track to another would save me hours every week.
Sorry about the link - it appears to go to the old version of the forum, and to a thread that doesn't exist any more - I'll redact it.
If you copy a clip and paste it somewhere else, the automation goes with it. Same thing applies to a group of clips. If you convert the copied clip into a unique copy, then you can open it in Waveform view and alter the audio, whilst retaining the automation data. So you can replace the audio if you want to. Effectively you have copied the automation data...
