There are two possibilities with this:
You could ask the police to consider the two as one continuous offence. I doubt they will because, looking at the map, there is a substantial intersection between those two locations, crossing Barnet Road. I imagine you must have slowed down or stopped at that junction.
You could ask a court to consider that, whilst they are separate offences, they were committed "on the same occasion." This would mean a fine and an endorsement for each, but only one lot of penalty points. "On the same occasion" is not defined so it would be up the court to decide that question.
