Combine same "Previous Usernames"

[CaulkClock]

Given we can change our names once a month, they're usually changed back after a fad dies out. The Previous Usernames mouseover shows each change, regardless if they're exactly the same as another. Would it be possible to combine the similar ones?

Example:

[Aussie]

I've noticed that too.

[WiiClock]

that'd be really cool especially because i can back and forth a lot
