I have had the Biz version for a while and I just got the personal one about 3 months ago. I SMed amex general inquiries and they denied my request to add the additional 5000 points for my personal card. I tried again over at social media, but they replied saying I already asked that question once and they were not going to over-ride the other CSRs decision.
So if you try, send to social media first, they may do it.
