We currently only have the ability to add one end date on a campaign. However, most campaigns are phased, and those phases have different deadlines. For instance, the ideation portion of a campaign often closes when review starts. Sometimes, ideation closes and voting and commenting stay open. To support these intermediary deadlines, admins have to set themselves reminders to make manual tweaks to the campaign, i.e. shutting off new submission and adjusting a campaign end date to update the countdown clock. It'd be great if they could set these end dates within the platform so phases could close more automatically.
