How to expand the height of/number of programs in the Start11 menu's Windows 7 style?

In Start10, with the Windows 7 style applied I could set the number of programs shown in the start menu so that the menu could expand as high as my monitor resolution would allow (I have 25 items).

I have a new Windows 11 machine, and purchased Start11, but I can't find in the Start11 menu anywhere where I can set this value after selecting the Windows 7 style, and it doesn't seem to increase the height automatically just by pinning more programs to the start menu; it appears to be stuck on 10.

How can I change Start11 to behave more like Start10? Without this feature to show a single column of applications, Windows-7 style, it loses about 90% of the appeal to me.
