Set a Unique ID

Is it Possible to Set a Unique ID for Spawn'd Objects, Let say i sapwn a Box with a lock on it, i wanna be able to spawn that box back in the location it was in, and belong to the same owner etc, i know about NET id but that changes with every new Instance, so if server restarts for example the box would have a different NET ID.

Thanks in advance

 

Pay attention to this scheme, then you might know how you technically could manage it (with care):

Code:

// Network.Server
public Networkable CreateNetworkable(uint uid)
{
    Networkable networkable = Pool.Get<Networkable>();
    networkable.ID = uid;
    networkable.sv = this;
    if (uid > this.lastValueGiven)
    {
        this.lastValueGiven = uid;
    }
    return networkable;
}
