Skipping covenant campaign

Is it possible to skip a covenant campaign in progress? Or does it have to be done from the very beginning?

If this is your first character and didn’t complete the covenant campaign yet you have to complete it from the beginning.
This counts for all 4 campaigns seperatly.

Afterwards you get skips on next characters.

I did complete it on another server. Does that count? So I have a character that completed it on Lightning’s Blade. I have one that is on stop 1 or 2 on Kazzak. How do I skip the one in progress on Kazzak?
