This is admittedly a very minor inconvenience, but does anyone know if it's possible to add an award ticket redeemed using VS points to my NH account? Right now If I want to make any changes to the ticket I have to enter my PNR and name on NH's website, instead of simply logging in. The Membership No. of mileage account provider field on NH's website shows my VS FF #, and I haven't figured out how to change it to my NH FF #.

(I've also tried searching but didn't find anything.)
