Change column amount of section for mobile and tablet

Hi there,

I understand the the Mobile editor is very limiting, meaning I am unable to change or assign a different column number for an image gallery.

I would like to target section : section[data-section-id="66ea541df5b3811360194441"] and only display "1" column, instead of "3" (Desktop) for mobile and tablet.

Any help in this is much appreciated. Thank you!
