How to separate html pages and Python code in Web2py

I am working on a new Web project (with Web2py) and I need to define organisation where page design and code will be separate and made by different peoples. Web designers will use tools like Pinegrow then give files to coders. I need to define rules where Web designers may update there work without coders' intervention (and vice versa). My question : is it possible with Web2py and what are the restrictions and 'best rules' ?
