Feature request: Use the background images specified in XMLTV within Plex

Currently Gracenote data supports background images for programmes. It would be great if Plex supported background images supplied in XMLTV files via the image tag. For example:

<programme start="20220331180000 +0000" stop="20220331190000 +0000" channel="channel-one.tv">
...
<image type="backdrop" size="3" orient="L" system="tvdb">https://tvdb.com/programme_one_backdrop_3.jpg</image>
...
</programme>

This is an officially supported tag from the XMLTV DTD.

(Also, it would be great if Plex were to provide a list of what XMLTV tags they look at. For example, I don’t believe the fact Plex can parse <sport> and <team> tags is documented anywhere)
