Alternative to trigger Retro Events when assignment work schedule is changed

Summary:

Content (required):

In the Current system when we change the work schedule to back dated the retro events are not triggering and hence it causing the incorrect payment to the users.

Expected Behavior: while changing the work schedule system should trigger the retro events while running the retro process

But currently we don't have any attribute to address Work Schedule changes to Retro event group.

Is there any alternative way to achieve this?

Any help would be greatly appreciated!
