I know with version control, or local history changes, it is possible, but possibility to roll back only current line would be faster and more comfortable.
Too late for the original poster, I'm sure, but this is now possible. When editing a file, the lines you have changed will have a colored bar beside their line numbers. Left click on this colored bar and select 'rollback lines'.
Not currently possible, please vote for https://youtrack.jetbrains.com/issue/IDEA-161441.
When using version control, you can revert changes in selected block - see https://youtrack.jetbrains.com/issue/IDEA-161441#comment=27-1620205
It is not possible ? Ehhh :(. Sure, I'll vote.

But you still can't change only one line from edited block.
