Automatically add needed sub productions to buildings when needed

For instance when I want to create an “advanced soldier” and I do not have an “iron shield” it would be nice if the “iron shield” production is auomatically added to the armor smith. Or at least I should be asked if I want that for all missing sub ressources.
That should work for all creations.

I’m personally no big fan of this. The settlers always been about managing the ressource chain yourself and I personally want to go back to this.
