Suggestions for a solution with multiple absence plans under single absence type

Summary

Purchased leave to be deducted after annual leave

Content

Hello experts,

Requirement:

1. Annual leave which allows 32 hours of negative balance and is accrued incrementally. 

2. There is purchased leave which is adjusted manually and is a front loaded plan. 

3. Sequence in which the leave should be deducted

1. Annual Leave balance is deducted to 0
2. Purchased Leave balance is deducted to 0
3. Annual Leave balance is deducted to a negative threshold depending on the countries requirements

What we initially setup was to have 2 plans annual leave with 32 hours negative and purchased leave and add both the plans to a single absence type with Annual leave as priority 1 and purchased leave as priority 2.
