Allow Carousel to be displayed vertically

This is definitely a niche use case, but would it be possible to not just move the Combat Carousel, but also rotate it?
I use Foundry for in-person play. Usually just for maps, but sometimes with tokens, and in those cases I use the Foundry combat tracker.
My players are seated around a wide screen TV on my table, along each long side.
This means that the tracker is upside down for half the players.
I would love to rotate it along a short side, so it would be easier to see for all the players, and only upside down for me as the GM, since I have my own GM view anyway.
Even more perfect would be if I could designate a center point when placing the tracker, so it would always build from the middle of that short side.
