I can't really see the use.
You could always just do ```M-: (sleep-foor xxx)``` in the macro.
Being time sensitive and waiting for abortion is a bit too dangerous
in my taste, either I am sure and do it everywhere or I want to accept
/ decline in cases like that.

What I usually do in cases like that is to make a macro that moves to
the next occurrence, then does the changes and then moves to just the
beginning of the next occurrence again.
That way I can just call the macro repeatedly and it will move forward
to the next place where a change will happen each time.
If I decide not to apply the macro I will skip forward, either
searching manually for the next occurrence or sometimes just moving
the point forward so the macro will edit the next occurrence instead.
