How to change Upcoming Campaign Items date

I would like to know how to update the date of an upcoming campaign item?

Any help will be appreciated.

That date is set based on the information inside the campaign builder. You would need to change the date or the timing inside of the campaign in order to change the date. However, that will change that information for everybody in the campaign.

Thanks Jeff for your answer. Yes I don’t want to change the campaign for everyone. I just want to extend the date for a particular customer, so that only for that customer things happen a bit late than usual.
Would there be any way of achieving that?

The only way to accomplish would be to create a separate sequence in the campaign that worked only for him.
