How to place an object and it stays until is moved again?

Hi everyone,

What would be the best way to set up an object so that it stays static after manipulated by the player?

So I would like the user to indicate where a certain object in the real world is in their playing space. Imagine there is a hardware box in the real world, and the user should in the game be able to mark it (by maybe marking with the trigger once the controller is at the same position as the object?).

I thought of a solution where there would be an object in VR and the user would place that object in the same position where the hardware is in the real world.

Please let me know if there are better ways to approach this.
