Issue description

Just like you did for having different sound in one resource definition

I want to have same thing for Structures, it would be good so we can make different trees variation as structures, and put them all in same structure mod element, so we don't have to make lot of structures mod element for the same thing 

Issue comments

Sorry for the bump, has this feature been added, I've seen that the GitHub has gone stale and so if not PLEASE add this.
