Match column width when adding new columns?

I think the Preview Builder would be a much quicker process, if the “Add Column Left/Right” function duplicated the size of the existing column. As an example, if I create a 3/12 column, and then “Add Column Right”, the new column would be created as a 3/12 (rather than a 4/12), or at least have a method of doing so (ie “Copy Column Left/Right”). Another option would be “Fill Row” method, wherein the user could select how many columns to add to fill the row. My least productive clicks are often spent adding and adjusting columns, and a more efficient method would be very welcome!

Great suggestion @PTSIoT !

Just want to highlight that the fill row option kind of already exists if you add a row from the bottom:
