Change 'Select' Dialogue Folder from Assets to Other Folder

When I hit the small circle to select an instance of something (in this case, an instance of the prefab TypeFire which contains a TypeFire script, which inherits from Type) it shows the empty Assets folder, which makes sense because there aren’t any Types stored there.


I want to navigate to the Types folder, which contains all the types, but I can’t see any way to do this.

I don’t want to move all my prefabs to the Assets folder without subfolders, so how should I solve this problem?

This doesnt show the Assets folder, it shows every assets.
You can’t select a prefab that way. You have to drag & drop them from the Project tab. Scriptableobjects will work for instance.
