Can we have a route for requesting Parallax/Extended Art treatments for cards and tokens in previous sets that never got that treatment?

Presuming there is a "Parallax team" as it were, as new sets continue to get this treatment, it would be wonderful to have a community route in for the most popular/desired "missed" cards to get this treatment.

Top of my list for example is Riders of the Mark from LOTR - nearly all the other red human typal cards from that set got the parallax treatment except for probably the best card in that archetype! It feels terrible having an otherwise fully-parallax deck with the main finisher not being in that style. The human tokens it produces already have parallax versions from other parallax-treated cards from that set, e.g. Rally at the Hornburg, so it feels like a quick job and would be much appreciated!

I'm sure there are others out there with specific "missed" cards/tokens in otherwise fully parallax-styled decks that they would love to request this style for, but there seems to be no information on why some cards were left out and how we can request this.

Parallax styles continue to be promoted in the shop and are much loved by many Arena fans, but not being able to "complete" a deck with all cards in this style is a real feel-bad that could be easily avoided.

Please upvote this suggestion if you're a frustrated parallax collector too!
