How to update a current MeshPart keeping the same MeshId?

Every time I make a change to an object made in Blender, I have to import it into the MeshId field inside the MeshPart.
However, every new import creates a new object, a new MeshId.
But I have several objects using the same MeshId inside Studio.
So I am forced to manually copy and paste the new MeshId created for all objects that used the old MeshId one by one.
It would be much easier if I just changed the content of the object that is in the current MeshId, without creating a new MeshId.
How to do this?


Unfortunately, there is no way (that I think exists) to create a new MeshPart that will keep the same MeshID.
