Time Condition

How can i add Time Condition only to one Extension or Queue? (all other Extensions and Queues should work without any Time Conditions).
I cannot find any TimeCondition settings in Extension/Queue settings…

Time conditions are usually applied as a destination for a DID. 555-3344 is sent to a Time Condition, and that time condition may have a destination as a queue/IVR/extension.

The Time Condition is usually in front of the destination, so it might not be possible to have a queue decide where to go. It works the same way with a Switchvox.
