By selecting multiple participants in the "Participating Member Settings" of the calendar and setting the "Participation Method" to "One Participating Member", reservations can be accepted for the number of participating members per date, assuming that all the members are free.

The number of people who can be selected in the "Participating Member Settings" is limited to 2 for the Free Plan and 12 for the Basic Plan and above.
(Reference) Select participating members.

Please note that TimeRex does not support scheduling methods such as group interviews or seminars, in which multiple reservations are accepted for one potential date.
