How do i snooze a specifc item to a later time without affecting everything in the snooze window

I have events come up for the day that sometimes i have to snooze them to a later time which i do at the bottom of the snooze window. However there is no snooze time next to each specific item. All items just seem to get snoozed to the same time frame ? Is there a way to snooze a specific event to a time without affecting all the events in the popup window. Thankz
