In P6, how to show a milestone's date to reflect the earliest start date of the group predecessors' activities rather than total

Dear All,

In P6, how to show a milestone's date to reflect the earliest start date of the group predecessors' activities rather than total float driving from the group predecessors' activities.

In the above snapshot, for my reporting purpose, I expect the start date for Activity ID300 from the group of predecessors should reflect the earliest start date of 01-08-2023 instead of total float driven predecessor's activity's start date of 29-08-2023
