passthrough original encode/tag date tags?

[Selur]

There is 'Config->Container->General->Adjust creation date to input'.
For mkv containers using, 'Config->MKV tagging->Auto load from input' might also work, if the DATE_ENCODED or another official mkv tag was used.

EDIT: i have found preserve metadata is apparently handled in ffmpeg via the command "-map_metadata 0" just not sure how to use this with hybrid.

That doesn't make sense the way Hybrid works, since that would only work if ffmpeg was used for muxing, which often isn't the case.
