Best way to enhance Z table maintenance view

Opinions please - what is the best way to enhance a generated Z table maintenance view?

1) Just add code where necessary and don't worry about another developer re-generating the screens and messing everything up

2) Could a BAdI be easily integrated in to a maintenance (PAI) screen? How?...and would it be a "proper" solution?

I've created a custom BAdI to be used in a custom upload program, but never used BAdIs in screen logic before.

3) Discard the generated screens and create my own

4) Other obvious solution I'm missing 😊

Thanks in advance.
