Undo only upto a certain point

Undo only upto a certain point

[deech]

Hi all,
Is there a way to undo only upto a certain point and no further. I
frequently run into this problem when I want to undo a large # of
changes (> 50) made using a keyboard macro. Right now I hold down
C-/ , try to time it out just right and frequently fail. Is there a
better way?

You can undo N steps only, by providing N as a prefix arg.
For example, `C-u 100 C-/' undoes 100 steps.

Unfortunately I frequently don't know how many steps need to be
undone. Is there a way of viewing a list of changes (maybe in another
buffer), setting a mark and undo everything upto that point?
