vim undo

Scenario:

- I open a file
- I make one big global change (C0)... say via substitute+regex
- I proceed to make more changes (C1, C2, ... Cn).

While *still editing the file* I realize that the initial change (C0)
was in error.

Can I undo the initial change (C0) and keep all the ensuing changes?

Or...

Go back to the initial state of the buffer, and make vim reapply all the
C1-Cn changes?

Standard vim only please, no plugins.

Thanks,

CJ
