Hi
Unfortunately not, the theme is built on bootstraps 12 column grid, for the shop page we use 3 columns for the sidebar, leaving 9 columns for the products which are 3 col width each, resulting in everything fitting nicely.
3 3 3 | 3
For pages, we use 4 col for the sidebar leaving 8 col for the page builder. We need to use 8 col for the page builder because of the widths you can set for the page builder assets, and it would not work if we used 9. For e.g if you set a page builder asset to 1/2 width, you can’t half 9 columns.
Hope this makes sense
