Upfront 4K breakpoint support

Upfront has only 3 breakpoints, would like to have a feature which supports 4K breakpoint for bigger scree sizes. Trying to design for 4K screen in Upfront doesn't seem to adapt smoothly in all screens, if I resize the browser, the site does not scale down properly.

Builders like webflow or mobirise, they do not seem to have the flexibility towards elements like Upfront, however the responsiveness is great in those builders, when compared to Upfront.

Would like an out of the box solution in Upfront which supports 4K breakpoints.
