Ability to have custom breakpoints in the UI designer

Hi team,

Would it be possible to expand the app's settings, to allow users to customise their 'breakpoints' in the UI designer?

There are 4 standard screen sizes, which cannot be changed.Ideally it would be great to allow users customise the default screen widths - 'breakpoints' in the UI designer. Even better, it would be really time-saving to be able to customise these 'breakpoints', which would also customise the class breakpoints in the actual BS css.

Thank you in advance
