Play it full resolution, full screen on a monitor turned to portrait orientation?

Is this possible or will this ever be possible?

The Switch version has this feature, but it was never added to the Steam version.
Everybody can turn their Switch on its side, but most monitors are not rotatable, which is probably why the developers didn't consider it worth the effort.

I guess you sort of can. Have set 'Tetris Effect Connected' to monitor 2 in game settings and also selected borderless in game settings. On the portrait monitor (2) It is full screen and quite immersive but Tetris game grid itself is not that big when fully zoomed in. Would be nice to have a dedicated portrait mode.
