GT-BMON6 Battery Monitor should be delivered with 200988051

Hi, I was informed that in package 2009834190 (UK) Battery Monitor won't be in and it is like that. So, is it possible to add the GT-BMON6 Battery Monitor (it has already been payed) to the package 200988051 which is on hold because of back order items and needs still time anyway. Would be great!
