Change Primary Assignment Flag from one assignment to another via HDL or Responsive UI

Summary:

We have added an assignment (-4) on 04/04/22 that currently has the primary assignment flag set to Y.

We have found out since that the start date of this assignment should be 07/04/22.

The previous primary assignment (-2) was changed from primary to non primary on 04/04/22.

Is there a way to change the primary assignment flag to the -2 assignment so we can change the start date of the -4 assignment and then change the -4 to primary assignment?
