TortoiseGit - where is the reset option for a branch?

Right now, the reset dialog can only be opened using the log dialog context menu.

cf. https://tortoisegit.org/docs/tortoisegit/tgit-dug-showlog.html

To add onto MrTux,

Go to the log dialog, right click on the commit you want to revert to and there should be a 'reset "current branch" to this' popup. If you want to clear all local changes in favor for this commit, then perform a Hard reset.
