Getting "Insider Offer" Extra Point on Existing Paid Full Booking?

Hello. We get the NCL Insider Offer emails but I'll admit I rarely read them as we book our cruises a year or more in advance due to scheduling PTO for work and the cost of "last minute" international business fares. Well, yesterday I did read it and not only is our cruise in March reduced, they're offering an extra Loyalty point. I've left our cruise consultant a VM this morning but wanted to see if anyone had any luck having something added/modified AFTER you've paid in full and after the free cancelation date? We'll make Saphire with this cruise but extra points are extra points. Thanks.
