Dopesheet selecting multiple objects at once

So I have 7 objects that are all moving in unsion, but I need them to animate one after another. The problem is that when I am trying to select them in the dopesheet, no matter what I do, every single one of them is selected at once.

Here's a picture of what I've got right now:

I've tried doing many things to stop them from being all selected, including the show only selected filter.

The objects were seperated in edit mode, which may have something to do with it.

• If you separated objects after they were animated then they will share the same animation, which will be shown in the Dopesheet. – Mr Zak Nov 8 '16 at 19:47
• Okay, but is there a way to make it so that when I select one it doesn't select them all? – MightyAlex200 Nov 8 '16 at 19:50
