Adjusting Gridlines in Wix Builder

Question:
How can we set the gridlines wider width points like 1440px. By default it is set to 980px

Wix Editor

Would love to know if you have an answer for this.

Currently trying to “build” a website for a client, first time using Wix. I’m absolutely astounded by the fact that the maximum container size is 980px.
