I have looked everywhere how to do it, but can't seem to be able to move a voice-over clip along the timeline or cut it and move sections or add new bit to a voice-over without having to delete and re-import the whole audio track onto timeline from scratch? Am I missing something?

Also if it is possible to edit voice-over and move it along the timeline, when you have animated a morph head what happens to the lipsynced mouth animations? Do you lose them or do they move along with it? Lipsyncing can take ages to animate and if a client gets back with requirements to change a bit of dialogue, what do you do? It would be great if there is a simple way to do it.

Many thanks.
