KDE Plasma: Create three equal sized tiles

I’d like to use a “tile” feature in any desktop I use. It looks like KDE Plasma Version 6.3.6 only supports “binary powers of two” when I personally like three tiles.

I have two monitors:
M1: width=2160 height=3840
M2: width=5120 height=1440

On M1 I would like to have three tiles of equal size arranged in the format “Top”, “Middle”, and “Bottom”. This is simple, because each tile must have dimensions width=2160 height=1280.

On M2 I would like to have three tiles of equal size arranged in the format “Left”, “Middle”, “Right”. This is less simple, because one tile must have dimensions width=1706 height=1440 and two tiles must have dimensions width=1707 height=1440.

I have tried using the “Super + T” command, however it appears as though I can only drag and drop panels, which is not the level of precision I would like to achieve.

Is there a way to support “three equal sized tiles” in KDE plasma?

Bonus points are awarded to someone who can point me in the direction of writing a static json/yaml/whatever file where I can specify my dimensions. I love declarative configurations stored in files! That way I don’t need to click many buttons when I install this software on a new machine!

have you tried using the tiling editor meta+T?

you can easily create 3 tiles and you use the shift+drag to move windows into the tile spaces.

I have tried this, and my post explains why I don’t find this to be a suitable solution.
Do you have any other ideas I could try?
