Blocks Extended to Two+ Columns

Hello all,

Does anyone know if there is a way to add a column in Page Builder that could be placed above two other columns. In Excel terms, I'd like cells A1 and A2 merged into one cell above separate cells B1 and B2. So, for example:

djd

I'm respectfully bumping this request, as it is the most important thing I'm trying to change in the default installation. Thank you very much in advance!

any developrs hav the ans please ??
