Proper way to edit a running autoresponder campaign ?

Hello guys,

I have a short 3 email autoresponder serie running.

I have just realized that the regular unsubscribe URL token is NOT a direct one click unsubscribe (which sucks imo) so apparently I need to replace it by DIRECT_UNSUBSCRIBE_URL in order to have real 1 click "no question asked" unsubscribe.

Now: how can I edit my 3 running campaigns/emails without generating a big mess?

[A] Should I just pause them, edit the template and "save and start" them at the end of the editing?

=> Also, does anyone knows if that DIRECT_UNSUBSCRIBE_URL will display some kind of confirmation message? Assuming this message is in english, how can I translate it?

Thanks a lot,
