construction upgrades

[Gazza]

Hey guys, some of you may have read this suggestion earlier, however after reading a post about suggestions, I thought I would make it easier to understand.

One thing I would like to see implemented into Project Zomboid is the modification/upgrade of constructed features, I.e. (wooden walls, crates, wooden doors, frames ect.)

The idea behind this is that as your character levels their construction abilities, they can then upgrade features previously constructed without having to tear them down (whilst losing marerials) and rebuilding them.
