Not that I know of, but I've done this and my remedy is usually
the following:

:%s/foo/bar/gc
(answer some y/n and screw one up)
q (quit the substitute)
u (undo the biffup)
:+,$s//~/&
(restart the previous command from the next line
searching for the same thing, replacing with the
same replacement, using the same flags)

which you can read about at

:help s~
:help :s_flags

If you've specified an original range of "%", then the above
works. Otherwise, you'd have to tweak the starting/ending range
on the 2nd/restarting command.
