In preferences> Defaults, one can set default Facility, Chain, Distributor and Studio. (screenshot 1)

If I understand it correctly, this should work in tandem with DCP metadata÷Advanced (screenshot 2)

1) Where is distributor?
2) when any of the defaults set, metadata should be prepopulated with it (once they get enabled or maybe they should be enabled and prepulated by default)
3) I think the Defaults are not documented here: https://dcpomatic.com/manual/html/ch22.html (or I am blind, which is possible)
4) Maybe a default territory could be set somewhere too?

(5) not sure if default languages for audio and subtitles would not make sense as a setting too - this is akin to https://dcpomatic.com/mantis/view.php?id=2078 as I keep setting the same values with DOM over and over)
