3DPhysics for prefabs/custom objects

[7ToGo]

Hello, I want to create a prefab/custom object that would consist of a 3D mesh and 3D boxes with 3DPhysics enabled for them, so that they could be used as elements of a collision mesh for that object. (This allows you to have convenient prefabs in the project with a custom complex collision consisting of a set of primitives)

Example:
The prefab is a simple 3D box with 3D physics enabled, in the project scene it stands at coordinates 160x60.
However, the mesh of its collision is being moved separately from the actual 3DBox to coordinates 0:0 - as in the prefab scene.

Other 3DPhysics objects in the scene can interact with it as usual, the problem being that its separated from the actual mesh of the object.

Is there any way to avoid this difference in the placement of the collision mesh and the object itself?

I think if you go into the cubes properties->behaviors->Advanced Properties, you can change the shape offset X and shape offset Y and it should fix it. I no joke just had this problem and idk why it does it but

I know, but offset would be useful if I only had 1 such object in the whole scene. I want to place several of them in the scene (for example, a wall module that has some kind of protrusions in addition to the base and their own cubes describing their collision), that is, the offset must be unique for each instance, and Gdevelop does not have an action to change the offset of a collision for a physical object, or I cannot find it.
