Archive Lists after campagining has ended

[spslater]

Is your feature request related to a problem? Please describe.
When I go to select the lists for a campaign or import, old lists that I no longer use appear at the top and it's annoying to have to scroll past them every time I need to select a list. I also worry that I'm going to accidentally click on the wrong one and not notice.

Describe the solution you'd like
A way to archive the Lists so that they don't appear in any of the drop down selections, but I'm still able to view who was on the list from the All Lists menu and see what campaigns were sent to those lists.
