You could design a route and name it something like: "Painters Palette", or have a spare baseboard off to the side of your route, where you keep a hodge podge cluster of all of your favorite textures and other assets.
Finding those assets in the first place is: one ... by ... one ... trial and error
The names and spellings of assets are a pain, as similar assets are set far apart on the list, ie: HyCube, and 86 Ft HighCube
You can rename any asset in its config file: username .... "whatever name you wish"
