clion git integration

A few questions about the git integration. I'd like to be able to do the following in the clion  / intellij IDE git integration:

1) Is it possible to commit directly into a commit in history ? UI would be like committing into a selected commit. Clion won't ask you for a commit message and behind the scenes it will create a commit and rebase it, fixing it up on the selected commit ?

2) Is there any friendly UI way to break apart commits? Either at the file level or hunk? Would look something like selecting a commit, then selecting a few files (or portions of file) from it before being asked for a commit message for the new commit? 

3) Like (2) move files between a pair of commits?  Two commits are selected and you can drag & drop files between them?
