Is there a way to edit the scene at a playhead time in the timeline?

When using the timeline, you can only edit the scene in the state set when the playhead is at 0:00.
Is there a way to make edits to the scene when it’s at different states set by modifications made in the timeline? In other words, if I scrubbed the playhead 5 seconds in, I’d like to make edits at that specific time.

The best you can do is copy the values in the inspector at the playhead time, turn off the preview mode in the timeline window and paste them back. When timeline is previewing it puts all the properties it uses in a ‘preview mode’.
