Layouts can have more than only table views inside of them. For example, another option you can do is to add detail views from transactions or accounts like this:

1. Search for desired item

Trigger the Select entity command (cmd + p), search for the item you want to add to your layout and select it.

2. Open item to the side

After selecting your item, trigger the Open to the side command.

A new panel with your item contained in it should be added into your layout afterwards.
