Usually, the schedule of the dives is based on the decision to either all dive wrecks within the depth range level of the whole group. So we all dive together in the 40-60M range or split the members of the group and dive as 2 separate teams.
For example, if within a group of 5 divers, 3 are Tech 2/CCR and 2 are Tech 1, either all the group will dive within 40-60M, or the group containing Tech 2/CCR will dive in the morning and the Tech 1 group will dive when the first group is back. In this case priority will be given to the group travelling the furthest to the wreck.
