Asking for clarification: build history only upon user interaction

[dbyy]

Is there a way that I can influence when the local history is being updated?
e.g.
Even if I made some changes on the code (and saved it), I don't want the changes being reflected in the history (yet).
Only when I think the current changes are final, than I want to execute a 'commit' of the changes to the local history.
Perhaps via a key command or right click -> option -> save, to store a new version of the file in the local history.
Is that possible?
Thanks
