Can historical work Work Schedules be pulled from View Calendar area

Summary:

We are trying to retrieve past work schedules for employees that were updated/deleted and needed for Absences taken. for context we are trying to run the Evaluate absence process for a point in the past and when we run the process the absences taken are turning to 0's and we have figured out that its because the work schedules for the employees were changed at some point and there is no history of the work schedules. We need to find a way to retrieve the old work schedules the employees had in order to update their absences taken
