Is it possible to narrow the time frame for a phish campaign?

Hello Everyone

My intention is to launch a campaign for <30 users.  I've tried this once, starting last Friday 7/24, and so far no emails have been sent.  The campaign duration is a minimum of one month.

Is there anyway for me to customize this?  I'd like to have the emails sent the same day as the launch.

Kind regards,

Geoff
