For a certain type of SRM pool X, we have ten resources available. However, the bookings get assigned to the same resources every time. For example, if three bookings are received without conflicts, each with one hour apart, they are most likely to use the same resource from pool X.

This scenario is causing some issues because if we want to extend one of the bookings by two hours, it would not be possible because the resource of pool X is already booked. Because of this, I wonder if it is possible to ask SRM to assign resources in a balanced way? so in the example, if three bookings are received each one will get booked with different resources of pool X.
