A big foundation of glide is that layouts become tied to sheets/tables. This happens at any level below the top level of a tab or a link to screen view. Your list would the the top level, so each list can be designed differently, but the details are the next level down and each list item then shares the same details layout. It’s designed this way so you can reference the same data in multiple places throughout the app without having to redesign the details screen every time, and any changes stay consistent throughout the app.
There are several ways to approach what you are trying to do, but it might help to first get a better understanding of why you want to have two tabs that point to the same data, and what exactly you want to be different between each tab.
