Another newbie question

We booked our tickets via 2 separate transactions as we were using 2 different companion certificates from 2 diff accounts. 4 of us total travelling BOS-PDX-OGG and return HNL-SEA-BOS. Currently sitting 3 in one row with the 4th sitting in the aisle seat accross the way. Should I do anything to let AS know that we are traveling together?

TIA
