Standard start scene

Is it possible to set a scene with ready-made objects at the start of the program?
For example, a cube was created, the scene was saved, and each time this cube or other object was opened, it immediately opened, without any import or scene opening.

Edit > Preference > Options 1 > Application > Auto save/load scene on app close/start.

So she saves everything at all.
Is it possible to make it interesting that this can be saved by pressing a button and only what was in the scene after clicking was saved by default?

I don't want to make things too complicated.
