Instead of having 3 symbols for Desktop / Tablet / Mobile -
if some columns are less than 66% or 33% it will Re-Stack into ROWS instead of COLUMNS (see Example.jpg)
This way, you’ll only have to use 1 Symbol for all 3 screens, instead of using 3 different Symbols.
There should be some CONDITIONAL like:
If Width 33% - Stack Vertical instead of Horizontal.
