OJS 3 Inviting multiple participants in a discussion at one time

At the end of the reviewing stage we need a final agreement on the acceptance of the article from the 3 managing editors of the journal. We see no other way as to add them as participants (all three seperatly) and then “adding a discussion” and inviting all three again seperately. Could this be manged in a way that one can add multiple persons at one time and select multiple participants for a disussion at one time?
