Self closing ceiling air discharge registers

[ed222]

Does anyone sell self closing registers like discharge registers for the ceiling, that would close when the system cycles off?
My upstairs ceiling registers leak cold air from the ducts and we do not use the upstairs much- unit is in the attic.

If you don't use it much in winters, be alerted of the condensate problems discussed here before.
