Indicating +1 on ww invites

Hi there! We had to cut down our invite list for Covid to make our venue work and are not inviting a lot of our friends' partners, especially local friends. We've told this to many of these friends and our WW website says we had to cut down the guest list, but is there a way to have WW invites be addressed to the person and whoever they are grouped with in our list? For example, if Jim and Nora Jones are linked then the email to Jim and/or Nora would indicate that they have a plus 1. Or do we have to collect the emails for every plus 1 we are inviting and say somewhere that only those that received an email are invited? Trying to avoid more awkwardness in an already awkward situation
