Stop Macro on 1132CU

[Art Todesco <actodesco@xxxxxxxxx>]

Does anyone know if you can stop a macro
on the 1132CU?  I presently start a
macro when a detector senses dusk.
Then, over the next hour lights are
turned on.  However, a passing
thunderstorm sometimes starts  the macro
and in a few minutes, it might get
bright again.  I do, then turn off all
the lights from another macro, however,
the first macro continues to run and,
depending on timing, turn on one or more
lights.  I know I could put in another
step to turn off the lights at x+50
minutes, but a "stop macro" would be
great.  Any ideas?
