syonym redirects should allow consistent settings between source and dest

[cwbooth5]

Let's say there are two keywords which mean the same thing.

go2 planets
go2 planet

Then let's say the user wanted everyone typing the planets keyword goes to the planet keyword. They'd just make a keyword for "planets" which heads to go2.url/planet.

That's the current way you'd redirect one keyword to another, using the target's behavior.

Now what about the expire date? They can be inconsistent. Could it be possible to have a checkbox to redirect internally to another list and keep consistent expire times between the two, so that when one expires, they both expire?
