Keybinding allowing to cycle through different grids

I really like this tool! However, it requires a lot of keybindings.

Would it be possible to add an option that cycles through the different grids?

e.g. a keybinding that cycles through the 3x2 grid options, another one for the 2x2 grid options and so on...

The issue does not name files or tests; start by locating the KWin script's keybinding and grid-selection handling. Define how cycling should work for each grid size, then verify that the new bindings cycle through the available options without requiring separate bindings for every grid.
