Hi Jamie,
You can actually copy and paste automation, by shift-click-dragging a selection box around the nodes you wish to copy. To copy them on the same track, just click and drag them with the option-modifier to the desired spot. To copy them to another track, hit apple-c, select the target track and set the desired timeline position with the playhead, then hit apple-v.
Alternatively, you could create an empty MIDI region over the nodes to be copied and just copy that region to wherever you want the automation to go. For this to work, you have to set your preference to either automatically copy all automation data with the object or at least have logic ask you whether you want to do so.
Hope this helped.
Tobias
