How to create adaptive section with different columns per breakpoint?

If you go to /admin/config/bootstrap-layout-builder/layouts you can add options to the list of choices for each layout including what you describe above

I have a similar task. I want to create 3 columns with a width of 100%, 50% and 50% (col-12 col-6 col-6).
But this is impossible

Or you can apply another patch to remove the layout requirement altogether (all layouts need to equal 12, but you need it to be a multiple of 12).
