@kmanstudios / @GregValiant thanks, I have to admit that was putting off opening Blender, I hadn't used it since version 2.6 a few years ago and I wasn't convinced I could really remember how to do anything. Turns out it's a bit like riding a bike, everything came back pretty fast, and any tools that I knew I wanted to use but couldn't find were easily locatable with a quick Google.
I didn't know about the 'per model settings', good tip, thanks!
