You can create and save multiple custom One Line Grid displays, accessible wherever One Line Grids are used within the MLS. The default One Line Grid display is also a customizable display provided by the MLS, and additional customized displays can be named by the users.
These customized One Line Grid displays can either be created from the One Line Grid Setup page, accessible from the Admin menu bar, or from the Search Results page by clicking the "Customize Grid" link.
