How to get Equivalent Hours for Day Entries from timecard to Fast Formula?

Summary:

We have a requirement where we need to calculate Total hours of certain time types and absence types in the timecard.

It's easily achievable for Payroll Time Types and Hours Absences. However, for Days and Calendar Days Absence types - we need to fetch the equivalent hours in the formula(TCR/TER). For Day and Calendar day absences, is there any direct option (other than value set) to get equivalent hours considering:

• We don't want to depend on Absence Daily Breakdown process and tables.
• There can be half day absences and we need equivalent hours for the absences.
